Valentines Day is an opportunity to show your partner (or your crush) how much they matter to you. Beyond flowers, chocolates or restaurant invites, jewelry is a popular gift for Valentines day. However, a well meant gift may turn out to even be a hazard to the giftee.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Cheap_Trendy_and_Toxic_High_Levels_of_Cadmium_in_Necklaces_Have_Been_Reported_Lately_93d25a7757.jpg" alt="Thermo Fisher Scientific: Cheap, Trendy – and Toxic?

That is the alarming conclusion of recent investigations by <a target="_blank" rel="noopener noreferrer" href="https://www.spiegel.de/wirtschaft/stiftung-warentest-findet-giftige-schwermetalle-in-angeboten-von-temu-und-shein-a-efb2057b-2377-4ce4-b2e0-07be01d00df0">Stiftung Warentest</a>, Germany’s leading consumer protection organization.<h3>A reputation under scrutiny</h3>Low prices, fast fashion, and endless product choices have made online platforms hugely popular across Europe. With just a few clicks, shoppers can order clothes, accessories, toys, and electronics at prices that seem almost too good to be true.In a large-scale product test, consumer advocates found serious safety deficiencies in many popular items sold on these platforms.The advice to consumers is equally clear: buyers should dispose of affected products immediately and think carefully about what they order in the future.<h3>Shockingly high levels of toxic metals</h3>One of the most concerning findings involved fashion jewelry. In the test, the cadmium concentration in two necklaces exceeded the <a target="_blank" rel="noopener noreferrer" href="https://de.euronews.com/2025/10/31/stiftung-warentest-giftige-schwermetalle-in-shein-und-temu-produkten">EU’s legal limit by 8,500 times.</a> It´s a cheaper alternative to safer metals like silver, zinc alloys, or stainless steel, is easy to work with, and looks good at first glance.However, cadmium is classified as carcinogenic and can cause serious kidney and bone damage. Because of its toxicity, it is subject to <a target="_blank" rel="noopener noreferrer" href="https://www.bvl.bund.de/SharedDocs/Pressemitteilungen/03_verbraucherprodukte/2020/2020_02_11_PI_Modeschmuck.html">strict limits</a> in the EU. Products that exceed these limits are considered unsafe and illegal to sell.Experts strongly warn against simply throwing such items into the household trash. Jewelry contaminated with cadmium or other heavy metals should be taken to a hazardous waste collection point.The <a target="_blank" rel="noopener noreferrer" href="https://www.euroconsumers.org/systemic-failures-in-product-compliance-on-temu-and-shein/">investigation</a> covered 162 products in total of which 54 were necklaces.The products were purchased online and tested in cooperation with consumer organizations from Denmark and Belgium.The results were sobering:<ul><li>110 of the 162 products failed to meet EU safety standards</li><li>Around 25% were rated “potentially dangerous”</li></ul><h3>A broader EU problem</h3>EU authorities regularly find toxic heavy metals such as <a target="_blank" rel="noopener noreferrer" href="https://pubmed.ncbi.nlm.nih.gov/33757252/">cadmium</a>, lead, and nickel in cheap imported jewelry. These substances can trigger severe allergies, damage organs like the liver and kidneys, and increase cancer risk.Although the EU’s rapid alert system (RAPEX) removes thousands of unsafe products from the market every year, experts warn that the number of untested items is far higher than what authorities can realistically monitor.In some laboratory tests, individual jewelry items were found to consist of up to 70% cadmium, making them legally “not marketable” in Germany and the EU.The takeaway for shoppers should be clear:<ul><li>Extremely low prices can come with hidden health and safety risks</li><li>Jewelry, children’s products, and electronics deserve extra caution</li><li>When in doubt, it’s safer to buy from sellers that clearly comply with EU regulations</li></ul><h3>How can we detect Cadmium in necklaces?</h3>Consumer product/jewelry guidance explicitly notes that cadmium in jewelry extracts can be measured by ICP-OES or ICP-MS after an extraction step.Cadmium in jewelry is often regulated at low levels (either as total content after digestion or as extractable/migratable Cd in simulated-use leaches). <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products?category=232&amp;instrumentationItems=83&amp;manufacturerItems=3">ICP-MS</a> is routinely chosen because it can quantify Cd at trace / ultra-trace levels with strong precision and accuracy.Using a Thermo Scientific iCAP MX Series ICP-MS for Cadmium (Cd) determination in necklaces/ jewellery makes sense because jewelry testing typically needs very low detection limits, high confidence in complex matrices, and defensible compliance data.<ul><li>Better interference control for Cd isotopes</li></ul>Cadmium has a range of isotopes available for analysis, but interferences need to be considered. Most isotopes are isobarically interfered by Tin (meaning that a given m/z range would be responding to both elements), the isotope typically monitored (111Cd) may be interfered by molybdenum (95Mo16O+). Since both elements can be found as well in jewelry, removing these interferences is critical to avoid false positives. The iCAP MX Series ICP-MS come with the powerful QCell collision/reaction cell to overcome interferences. The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1487">Thermo Scientific iCAP MSX ICP-MS</a> uses kinetic energy discrimination (KED) with helium gas, a generic way for reducing polyatomic interferences broadly across the mass range. The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1487">Thermo Scientific iCAP MTX ICP-MS</a> can utilize reactive gases (in many applications O2) to further improve detectability and sensitivity – a powerful asset for laboratories analysing a wide range of sample types, which on top may “messy” – i.e. containing platings, alloys, pigments, fillers, and adhesives.<ul><li>Works with recognized jewelry test workflows</li></ul>Because necklaces and other consumer products often arrive as multiple distinct batches, repeats, blanks, spikes, and QC checks must be performed. All iCAP MX &nbsp;Series ICP-MS systems are positioned for high-throughput routine trace elemental analysis, helping labs to simplify workflows and keeping uptime high—useful in contract/compliance labs.<h3>Conclusion</h3>The findings underscore a troubling reality: many ultra-cheap products sold via online marketplaces pose real health and safety risks and routinely fail to meet EU standards. From toxic heavy metals in jewelry to hazardous chemicals in baby products, the consequences for consumers can be severe. Addressing this challenge requires both stronger regulatory oversight and reliable analytical testing. Advanced techniques such as ICP-MS play a critical role by enabling laboratories to accurately detect trace contaminants like cadmium across complex samples, helping authorities and manufacturers ensure compliance. Until safeguards improve, consumers are urged to remain vigilant—because when safety is compromised, a low price is no bargain at all.<h3>Additional resources</h3><ul><li><a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/mass-spectrometry/inductively-coupled-plasma-mass-spectrometry-icp-ms/quadrupole-icp-ms-systems.html">Quadrupole ICP-MS Systems</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/br_003092_tea_icp_ms_icap_mtx_discovery_br003092_em_en_e92e76f052.pdf">Ignite your confidence: iCAP MTX triple quadrupole ICP-MS</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1489">Qtegra ISDS software</a></li></ul><h3>Join us for free local language webinars in 2026</h3><h5>English</h5><ul><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/webinar/5795">Lunch and Learn Tips and Tricks Series: Qtegra Part 1</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/webinar/5976">Lunch and Learn Tips and Tricks Series: Qtegra Part 2</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/webinar/5977">Lunch and Learn Tips and Tricks Series: Trace Elemental Analysis (ICP-OES &amp; ICP-MS)</a></li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/webinar/5978">Trace Elemental Analysis: Ask the Expert</a></li></ul><h5>Deutsch</h5><ul><li>19.

Cheap, Trendy – and Toxic? High Levels of Cadmium in Necklaces Have Been Reported Lately

Traditional ducted fume hoods remain the gold standard for chemical containment in most laboratories, but several innovative alternatives can provide effective protection while offering unique advantages. These alternatives include glove boxes, snorkel systems, and specialized containment units that address specific laboratory needs while potentially reducing energy consumption and installation complexity.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Organomation_Alternatives_to_Traditional_Fume_Hoods_A_Comprehensive_Guide_to_Laboratory_Containment_Solutions_9c39f814df.jpg" alt="Organomation: Alternatives to Traditional Fume Hoods: A Comprehensive Guide to Laboratory Containment Solutions" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Organomation_Alternatives_to_Traditional_Fume_Hoods_A_Comprehensive_Guide_to_Laboratory_Containment_Solutions_9c39f814df.jpg 208w," sizes="100vw" width="2016" height="1512"><h3>Glove Boxes: Maximum Containment for High-Risk Materials</h3>Glove boxes, also known as isolation enclosures, represent the highest level of containment available for laboratory operations. These fully enclosed systems create a complete physical barrier between operators and hazardous materials while maintaining precise environmental control.<h4>Key Features and Applications</h4>Glove boxes consist of hermetically sealed stainless steel or transparent enclosures equipped with integrated gloves that allow manipulation without breaking containment. Modern systems include sophisticated transfer airlocks, sensors, regulators, and automatic safety flow systems that compensate for pressure drops or accidental containment breaches.These systems excel in applications requiring extremely low occupational exposure limits (OELs). For materials classified as OEB 4 (1-50 μg/m³) or OEB 5 (&lt;1 μg/m³), glove boxes provide containment levels as low as 0.1 μg/m³ or even 0.01 μg/m³. This makes them essential for handling highly potent pharmaceutical compounds, radioactive materials, and other extremely hazardous substances.<h4>Specialized Configurations</h4>The versatility of glove box technology extends to numerous specialized applications. Compounding Aseptic Isolators (CAI) create positive pressure environments for sterile pharmaceutical compounding, meeting USP 797 requirements. Conversely, Compounding Aseptic Containment Isolators (CACI) operate under negative pressure for handling hazardous drugs per USP 800 guidelines.Inert atmosphere glove boxes utilize nitrogen or argon purging to create oxygen-free environments essential for moisture-sensitive materials and anaerobic research. These systems feature automated purge cycles and one-touch operation for seamless anaerobic transitions.<h4>Construction Materials and Performance</h4>Stainless steel construction (316L grade) provides optimal chemical resistance and durability, with continuous seam welds and wide radius corners facilitating easy decontamination. Leak rates typically specification below 0.05% chamber volume per hour, verified through pressure decay testing. Advanced systems incorporate built-in sterilization capabilities using vaporized hydrogen peroxide (VHP) generators for thorough decontamination between uses.<h4>Advantages and Limitations</h4>Glove boxes offer unparalleled containment performance with complete environmental isolation, precise atmospheric control, and robust decontamination capabilities. The closed design eliminates airflow disturbances that can compromise containment in open-front systems.However, glove boxes require larger footprints, higher initial investment, and more complex maintenance compared to open containment systems. The enclosed design may limit accessibility for larger equipment or rapid material transfers, and extended use can cause operator fatigue due to the ergonomic constraints of glove manipulation.<h3>Snorkel Systems: Localized Fume Extraction</h3>Snorkel systems, also known as articulating extraction arms or fume extraction arms, provide targeted fume capture at the source while maintaining workspace flexibility.<h4>Design and Operation</h4>These systems feature flexible, articulating arms typically 3-8 inches in diameter with working radii ranging from 3-14 feet. The arms incorporate three adjustable joints allowing 360-degree rotation and positioning flexibility. Standard configurations handle airflow rates from 30-1000 CFM depending on arm diameter and application requirements.Multiple specialized configurations address specific laboratory needs. The Original model provides general-purpose fume extraction for standard laboratory applications. ESD/EX models incorporate conductive materials to eliminate electrostatic discharge risks in electronic environments. CHEM models feature double anodized aluminum construction for enhanced corrosion resistance in aggressive chemical environments.<h4>Installation and Integration</h4>Snorkel systems mount to walls, ceilings, workbenches, or specialized support structures. They integrate with facility HVAC systems or standalone filtration units depending on application requirements. Mobile configurations with integrated collectors provide complete portability for applications requiring frequent repositioning.Advanced mounting systems include swing boom configurations for extended reach applications (18-35 feet) and rail-mounted trolley systems for linear positioning along extended work areas. These systems require minimal operator force for positioning and repositioning.<h4>Hood Options and Customization</h4>Extraction hoods vary based on application requirements. Transparent dome hoods optimize visibility for precision work while providing effective capture for high-dispersion particles. Metal hoods offer enhanced durability and chemical resistance for aggressive environments. Specialized hood geometries optimize capture efficiency for specific processes like chromatography or analytical instrumentation.<h4>Performance and Applications</h4>Snorkel systems excel in applications requiring localized fume extraction from specific equipment like chromatographs, analytical instruments, or small-scale chemical processes. They provide effective capture distances of 12-20 inches from the source with capture areas up to 20 inches in diameter.These systems prove particularly valuable in laboratories with limited space, flexible furniture arrangements, or applications where full fume hood installation is impractical. Educational laboratories benefit from their overhead mounting that preserves floor space while providing necessary ventilation.<h4>Energy Efficiency Considerations</h4>Snorkel systems typically require lower airflow rates than full-sized fume hoods, reducing energy consumption and HVAC demands. When integrated with variable speed controls and demand-based operation, they provide energy-efficient alternatives to constant-volume hood operation.<h3>Ductless Fume Hoods: Energy-Efficient Alternatives</h3>Ductless fume hoods represent a growing alternative to traditional ducted systems, offering significant energy savings and installation flexibility while maintaining safety standards.<h4>Energy Performance Advantages</h4>Ductless systems achieve remarkable energy efficiency improvements over traditional ducted hoods. Studies indicate energy efficiency improvements of 18-25 times compared to total exhaust systems, primarily through air recirculation rather than continuous exhaust of conditioned air. This translates to substantial reductions in HVAC loads and operational costs.A comparative analysis of a hypothetical 30-hood facility demonstrated that ductless systems consume only 2.4 kBTU per square foot annually compared to 127.5 kBTU for constant volume hoods and 74.1 kBTU for VAV systems. Carbon dioxide emissions similarly decrease from 873 tons annually for constant volume systems to just 55 tons for ductless alternatives.<h4>Filtration Technology and Safety</h4>Modern ductless hoods employ sophisticated multi-stage filtration systems combining carbon, HEPA, and specialized chemical filters. Advanced monitoring systems continuously assess filter performance and provide alerts when replacement is required. These systems maintain face velocities of 100 feet per minute, meeting OSHA recommendations while achieving ASHRAE 110 certification standards.Filter replacement costs range from $350-2,000 annually, representing significant savings compared to ongoing HVAC operational costs of ducted systems. Filter life varies based on application but typically extends 6-12 months under normal laboratory conditions.<h4>Installation and Flexibility Benefits</h4>Ductless hoods arrive fully certified and ready for immediate use without requiring building modifications or HVAC integration. This eliminates lengthy installation timelines and coordination requirements associated with ducted systems. Mobile configurations provide additional flexibility for laboratories requiring equipment relocation.The plug-and-play nature of ductless systems allows rapid deployment and adaptation to changing laboratory needs without facility downtime or infrastructure modifications.<h4>Application Limitations and Considerations</h4>Ductless systems prove most effective for applications involving naturally evaporating chemicals in limited volumes. They are not suitable for heated chemicals, highly volatile solvents, or applications generating large volumes of hazardous vapors. Regular filter monitoring and replacement are essential to maintain protection effectiveness.<h3>Specialized Containment Solutions</h3>Beyond traditional glove boxes and snorkel systems, several specialized containment solutions address specific laboratory needs.<h4>Downflow Booths</h4>Downflow booths utilize unidirectional airflow to carry contaminants away from operator breathing zones into low-level exhaust systems. These systems prove effective for powder handling operations requiring containment levels of 50-100 μg/m³.Recirculatory configurations suit powder operations while single-pass designs handle applications involving solvents or vapor generation. HEPA filtration and controlled airflow patterns (typically 90 FPM) provide effective containment while maintaining operator accessibility.<h4>Mobile Fume Extractors</h4>Portable fume extraction units combine the benefits of source capture with complete mobility. These self-contained systems feature integrated filtration, typically 3-stage systems with aluminum mesh pre-filters, MERV 15 cartridge filters, and activated carbon after-filters.Units range from 750-1200 CFM capacity with 6-8 inch diameter extraction arms in lengths from 7-14 feet. Advanced models incorporate pulse-cleaning systems extending filter life 6-7 times beyond traditional reverse-pulse systems.<h4>Biosafety Cabinets and Biological Containment</h4>While primarily designed for biological applications, Class III biosafety cabinets function as glove box systems for maximum biological containment. These systems provide complete enclosure with HEPA filtration for handling BSL-3 and BSL-4 materials.Class II biosafety cabinets offer open-front operation with HEPA filtration for lower-risk biological materials while providing some chemical containment capabilities for limited applications.<h3>Selection Criteria and Implementation Considerations</h3><h4>Material Hazard Assessment</h4>The selection of appropriate fume hood alternatives depends primarily on the occupational exposure limits and toxicological properties of materials being handled. OEB classifications provide guidance for containment requirements:<ul><li>OEB 1-2 (100-5000 μg/m³): Standard downflow booths with minimal additional controls</li><li>OEB 3 (10-100 μg/m³): Enhanced downflow booths or limited containment systems</li><li>OEB 4 (1-10 μg/m³): Specialized containment or glove box systems recommended</li><li>OEB 5 (&lt;1 μg/m³): Full isolation systems required</li></ul><h4>Economic Considerations</h4>Initial investment costs vary significantly among alternatives. Ductless hoods typically require lower upfront investment due to eliminated infrastructure requirements. Glove boxes represent higher initial costs but provide superior long-term containment assurance for high-risk materials.Operational costs favor ductless systems through reduced energy consumption, while glove boxes may require higher maintenance but offer lower risk exposure costs.<h4>Laboratory Design Integration</h4>Space constraints and laboratory layout significantly influence alternative selection. Snorkel systems optimize overhead space utilization while maintaining floor accessibility. Ductless hoods provide location flexibility without ducting constraints. Glove boxes require dedicated space but offer maximum containment assurance.Future laboratory needs and potential application changes should inform selection decisions, with modular and mobile solutions providing greater adaptability.The landscape of fume hood alternatives continues expanding with advancing filtration technology, improved energy efficiency, and enhanced safety monitoring systems. Each alternative offers distinct advantages addressing specific laboratory requirements while potentially providing economic and operational benefits over traditional ducted systems. Proper selection requires careful assessment of material hazards, operational requirements, and facility constraints to ensure both safety and efficiency objectives are met.

Agilent Technologies: UV-Vis Spectroscopy for Quality Assessment of Paprika as per ASTA Method 20.1</h3>From sample prep to analysis using the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=Cary+3500">Agilent Cary 3500 Multicell UV-Vis</a><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_paprika_uv_vis_cary_5994_8612en_agilent_d903914b39.pdf">Full PDF for download</a></li></ul>Paprika is a widely used spice valued for its deep red color and characteristic flavor, contributing to its prominence in both culinary and commercial applications. As a high‑demand commodity produced from dried capsicum pods, paprika is subject to quality variation and adulteration, which can compromise product authenticity, consumer trust, and regulatory compliance. UV-Visible (UV-Vis) spectroscopy is a rapid, reproducible analytical technique for evaluating paprika quality by quantifying pigment concentration. In paprika, color intensity primarily arises from carotenoid compounds, and is commonly assessed using the ASTA Method 20.11 – a well-established industry standard that commercially grades paprika samples as a numerical ASTA color value.In this application note, we used an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=Cary+3500">Agilent Cary 3500 Multicell UV-Vis spectrophotometer</a> and <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=UV+Workstation+software">Agilent Cary UV Workstation software</a> to determine the ASTA color value of two commercial paprika samples. The measurements were performed in accordance with ASTA Method 20.1 for the determination of extractable color in capsicums and their&nbsp;oleoresins.<h4>Results and discussion</h4><h5>Paprika samples' analysis&nbsp;</h5>ASTA Method 20.1 measures the color intensity of paprika by extracting pigments with acetone and recording absorbance at 460 nm. The absorbance reading, along with sample weight is then used to calculate the ASTA color value. The ASTA color value is a crucial quality parameter for paprika and other spices, as it indicates the intensity and vibrancy of the red color, which is a key characteristic for consumers and food manufacturers. In this study, the two extracted paprika samples were each measured three times to produce triplicate results (Table 4). Sample 1 had a corrected ASTA color value of approximately 103, and sample 2 had a corrected ASTA color value of approximately 61, indicating a lower color intensity. The corrected ASTA color value was automatically generated in an easy-to-read table of values, and a scan report was automatically exported into a user-defined location.<h4>Conclusion&nbsp;</h4>The Agilent Cary 3500 Multicell UV-Vis spectrophotometer with Agilent Cary UV Workstation software enabled fast, reliable, and standardized quality assessment of paprika samples. Using the well-established industry method, ASTA 20.1, the Cary 3500 system provided precise quantification of carotenoid pigments, supporting grading categorization. The high-throughput multicell design of the Cary 3500 Multicell UV-Vis spectrophotometer allows simultaneous measurement of up to seven samples and a reference, improving efficiency and minimizing variability. The Cary UV Workstation software simplifies data acquisition and analysis with intuitive spectral features such as the End of sequence analysis tool, which can be applied automatically to any scan method, and spectra comparisons through the Load spectrum tool. From sample absorbance measurement to final reporting, the Cary 3500 system eliminated the need for manual data processing or external tools, minimizing complexity and facilitating confidence.<h3>2. Metrohm: NIRS analysis of forages</h3>Multiparameter determination in a few seconds<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_nir_131_download_2f897ff7f5.pdf">Full PDF for download</a></li></ul>Forages are plants or parts of plants eaten by both livestock and wildlife. Forages provide bulk, help with weight maintenance, and combat several issues [1]. Alfalfa forage is high in protein—well-suited to promote muscle mass in beef cattle or to increase the production of dairy cows [2]. Alfalfa is also commonly used for horse feed. These animals require forages with good palatability along with high digestibility, intake potential, and protein levels, thus increasing the demand for alfalfa and other high-quality feeds. Farmers have responded by producing even higherquality alfalfa in recent years. Since forage quality depends on chemical, biological, and dynamic properties, both measured and calculated methods must be used. Standard alfalfa assays measure neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), ash, moisture, and protein. For alfalfa pellets, the mean particle size is also important. Near-infrared spectroscopy (NIRS) offers rapid and reliable prediction of fat, moisture, crude protein, fiber, ash and starch in a few seconds and without sample preparation.<h4>EXPERIMENTAL EQUIPMENT</h4>Samples of alfalfa (including fresh alfalfa, alfalfa pellets, and alfalfa cubes) were analyzed on a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=220&amp;search=NIR+Analyzer">Metrohm NIR Analyzer</a>. All measurements were performed in reflection mode using the large cup. The samples were measured in rotation to collect spectral data from several areas. Spectral averaging of signals from several spots helped to reduce sample inhomogeneity. The reference values were measured according to ISO norms described at the end of this Application Note. Metrohm software was used for all data acquisition and prediction model development.<h4>CONCLUSION&nbsp;</h4>This Application Note demonstrates the feasibility to determine multiple key parameters of alfalfa forage with NIR spectroscopy. Several analytical methods are usually required to measure key quality parameters for forage (Table 4). NIRS forage analysis enables a highly accurate, cost-effective, and fast alternative.<h3>3. Shimadzu: Analysis of Heavy Metals in Baby Food Using ICP-MS</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01039_en_c563bb1b82.pdf">Full PDF for download</a></li></ul><h4>User Benefits</h4><ul><li>Heavy metals in various baby foods can be analyzed simultaneously with sufficient sensitivity.</li><li>Stable analysis can be performed even for baby foods with high matrix content.</li><li>Using the standard LabSolutions ICPMS rinse function, the time to clean the sample introduction system is minimized, which prevents carryover.</li></ul>Infants’ metabolic pathways are still developing, and because of their lower body weight, they are known to be more susceptible to the effects of harmful substances. In the United States, the Baby Food Safety Act 20211), and in the EU, Commission Regulation (EU) 2023/9152) and Commission Regulation (EU) 2024/19873) require the control of toxic metals contained in baby foods. ICP-MS is suitable for the analysis of trace amounts of toxic metal elements because it can perform multi-element simultaneous analysis with high sensitivity.However, baby foods vary in matrix composition, which raises concerns about non-spectral interferences and long-term stability during ICP-MS analysis. This Application News describes the analysis of five baby foods with different matrices using the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=ICPMS-2040%2F2050">ICPMS-2040/2050</a> (Fig. 1). Additionally, spike recovery tests and long-term stability were assessed based on the Food and Drug Administration (FDA) Elemental Analysis Manual (EAM) Section 4.74).<h4>Equipment Configuration and Analysis Conditions&nbsp;</h4>The equipment configuration is shown in Table 2. To reduce running costs, a mini-torch with lower argon gas consumption compared to conventional torches was used for analysis. Additionally, to streamline sample preparation, an Online Internal Standard Kit was utilized for online addition.&nbsp;The analysis conditions are detailed in Table 3. After analyzing high-concentration samples, the sample introduction system can influence the analysis values of subsequent samples (carryover). If carryover occurs, re-measurement is necessary, which consumes additional time and samples. With LabSolutions ICPMS, rinse solutions can be set for each sample, enabling effective cleaning in minimal time. Normal cleaning was performed using pure water (Rinse solution 1), and an additional acid rinse solution (Rinse solution 2) was introduced only after high-concentration samples.For example, Table 4 shows the difference in carryover concentration when measuring a blank sample after introducing a sample with a CCV concentration, comparing the case where rinse solution 2 is added for an additional 240 seconds to the case where it is not. Among the elements measured this time, Se and Hg tend to have a higher risk of carryover, but by introducing rinse solution 2, carryover was reduced to below the detection limit. Moreover, even if unexpectedly high-concentration samples are introduced, the Extended Rinsing function allows for automatic additional rinsing (Fig. 3). This eliminates the need to repeatedly check analysis values or to set a uniform cleaning time uniformly, thus reducing the verification effort, the amount of rinse solution required, and the analysis time while preventing carryover.&nbsp;Furthermore, to minimize time spent cleaning the sample introduction system, ProActive Rinsing was used (Fig. 4). When measuring multiple samples, starting the rinse in advance during measurement reduces the measurement time for subsequentsamples.<h4>Conclusion&nbsp;</h4>In this Application News, elemental analysis of baby food was conducted using the ICPMS-2040/2050. We achieved detection limits that met stringent standards. The spike recovery tests yielded good results for all samples with different matrices, confirming the validity of the analysis. Additionally, we analyzed 50 samples of infant formula with a high matrix over approximately six hours and confirmed good stability. The ICPMS-2040/2050 offers high sensitivity, accurate analysis, and good stability.

The degree of oxidation depends on various factors such as the type of meat, the fat content, the storage temperature, the availability of oxygen and the type of packaging1, 2. To prevent oxidation, synthetic antioxidants are commonly added to meat products, but consumers are now demanding more natural products3. Several studies have been carried out to evaluate the antioxidant activity of many essential oils or extracts from plants or spices such as rosemary, cinnamon or oregano, and the new trend is to develop innovative packaging by adding these natural antioxidants directly to the packaging materials4–6. These materials, often films, are known as “active packaging” because they enable the controlled release of active agents either on the surface or in the internal atmosphere of the product, or by trapping the radicals responsible for harmful effects on food quality. However, the antioxidant performance of these films must be accurately determined to enable the selection of the right packaging for each foodstuff.&nbsp;Among all the techniques available, Raman spectroscopy is a promising candidate for detecting most molecular species with high specificity and sensitivity, particularly in the presence of Surface-Enhanced Raman Scattering (SERS). Indeed, SERS is a physical phenomenon that occurs in the presence of a rough nano-structured metallic surface that causes the intensification of Raman signals from molecules adsorbed to the surface thanks to the combination of a chemical effect and an electromagnetic effect7 . The metals used are generally gold or silver, which can be prepared by electrochemical roughening, metallic coating, or deposition of nanoparticles (often in a colloidal form). Commercial solutions are available, but many researchers prefer to create their own SERS substrates. The scope of this work is to investigate the potential of a home-made SERS substrate to compare the lipid oxidation over time in ground pork preserved either in a low-density polyethylene (LDPE) conventional packaging or in an active packaging containing oregano extract.<h4>Material and method&nbsp;</h4>Fresh ground pork meat was purchased in bulk from a local supermarket and 22 g samples of meat were placed in 5-cm diameter polystyrene Petri dishes. Each sample was covered with an active film and packed in an LDPE bag under a normal atmosphere. Reference samples were also prepared using conventional LDPE films. All samples were stored in a refrigerator at 5 °C and their lipid extracts were analyzed after 0, 7, 9, 11, 14 and 16 days using a home-made SERS substrate based on silver nanoparticles deposited on a glass Petri dish. A special home-made cooling system was used to perform the analyses at low temperature and SERS spectra were measured at -2 °C on a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2239">Thermo Scientific™ DXR3 Raman Microscope</a> (Waltham, MA, USA) with a 532 nm laser source, a 900 lines/mm grating covering the 50-3500 cm-1 spectral range and an x10 objective (NA 0.40). The laser power was set at 5&nbsp;mW, and 20 exposures of 30 s each were selected to acquire all data. Thermo Scientific™ OMNIC™ v. 9.2 software was used for data collection and analysis. All the measurements were performed in triplicate. As the decrease in the peak at 1655&nbsp;cm-1 (stretching of C=C bonds from unsaturation) can be attributed to lipid peroxidation, and the 1439 cm-1 (scissoring deformation of CH2) is not affected by it, the area ratio between 1655 cm-1 and 1439 cm-1 bands was calculated to follow the lipid oxidation.<h4>Conclusion&nbsp;</h4>The effectiveness of a home-made SERS substrate coupled with a home-made cooling system was demonstrated for monitoring lipid oxidation in packaged ground pork meat over time. The advantages of this technique are its speed and the minimal sample handling requirements. An improvement factor of the order of 107 over conventional Raman was observed. This study also confirmed the greater efficacy of active packaging containing oregano extracts against lipid oxidation in ground pork, compared to conventional LDPE packaging.
