Agilent Technologies: Black Pepper Origin Differentiation Using Large ICP-MS Datasets and Chemometric Tools</h3>Elemental profiling using an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;search=7850+ICP-MS">Agilent 7850 ICP-MS</a> and Agilent <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;search=Mass+Profiler+Professional+software">Mass Profiler Professional (MPP) software</a><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_black_pepper_origin_7850_icp_ms_5994_8741en_agilent_7c190968ef.pdf">Full PDF for download</a></li></ul>Black pepper’s high value and global demand are drivers for economically motivated adulteration, a fraudulent practice that can pose public health risks. Because black pepper is most often sold in ground, crushed, or mixed forms, its supply chain is difficult to monitor and manage. Also, consumer campaigns against deforestation and the European Union Regulation on Deforestation-free (EUDR) products have increased calls for greater sourcing transparency. Products with a known geographical indication can demand a higher price. Companies do not want to become implicated in false claims about the sourcing of products, and many are keen to have full visibility of their products’ origin. To address this need, the European Commission has established the Protected Geographical Indication (PGI) system to protect regional specific products, thereby promoting their unique characteristics based on geographical origin and traditional competence of production. The PGI scheme has increased the demand for detailed information regarding the geographical source of food products, a trend that is likely to continue as EUDR is implemented across the EU and associated markets. Verifying the geographical origin of black pepper using elemental fingerprints is highly relevant to protecting value chain stakeholders, ensuring both quality and traceability while upholding the principles of food integrity.&nbsp;Several analytical methods can be used for profiling certain elements in foods. However, inductively coupled plasma mass spectrometry (ICP-MS) is unique because of its rapid throughput, multi-element capability, ultratrace sensitivity, isotopic analysis, versatility across sample types, low sample volume requirements, compliance with regulatory requirements, and low cost.3&nbsp;The Agilent 7850 ICP-MS is equipped with an Octopole Reaction System (ORS4 ), a collision/reaction cell (CRC) that uses helium (He) gas and Kinetic Energy Discrimination (KED) to remove polyatomic interferences on key analytes.4 If left unchecked, these interferences can affect data accuracy in complex food products. The integration of the 7850 with Agilent ICP-MS MassHunter software streamlines data analysis. When integrated with chemometric analysis, ICP-MS demonstrates high precision in multi-elemental profiling of diverse food matrices, effectively distinguishing their geographical origin.5&nbsp;In this study, 150 black pepper samples from five countries (Brazil, Cambodia, India, Indonesia, Vietnam) were analyzed using the 7850 ICP-MS to obtain elemental fingerprints of the samples. Agilent Mass Profiler Professional (MPP) software was used to process the ICP-MS elemental data and to construct chemometric models for distinguishing the geographical origin of the samples, as adapted from Chilaka et al.5<h4>Experimental&nbsp;</h4><h5>Instrumentation&nbsp;</h5>An <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;search=7850+ICP-MS">Agilent 7850 single-quadrupole ICP-MS</a> was used for the analysis of 38 elements in the black pepper samples. Sample introduction was performed via a peristaltic pump connected to an Agilent MicroMist nebulizer and an Agilent SPS 4 autosampler. All elements were measured using helium collision (He KED) mode, except for boron (B), which was analyzed in no gas mode. Instrument control was performed using <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;search=MassHunter">Agilent ICP-MS MassHunter 5.1 software</a>, and data processing was conducted using <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;search=Mass+Profiler+Professional+software">Agilent MPP software</a>, version 15.1. Instrument operating conditions as shown in Table 1.<h4>Conclusion&nbsp;</h4>This study investigated the potential of ICP-MS elemental profiling coupled with chemometric analysis for geographical origin discrimination of black pepper samples from five countries, including Brazil, Cambodia, India, Indonesia, and Vietnam. A total of 38 elements was measured in 150 black pepper samples using the Agilent 7850 ICP-MS. Chemometric analysis was performed on the ICP-MS elemental data using Agilent Mass Profiler Professional (MPP) software. The PCA analysis exhibited satisfactory reliability and classification rates and demonstrated potential for the authentication of the geographical origin of black pepper. However, the separation of the Cambodian and Vietnamese samples was less distinct than the other groups, revealing potential similarities in elemental profiling between the bordering countries, which share similar climatic, geological, and agricultural conditions. Using LDA and RF classification models on the black pepper test set, we achieved a high overall accuracy in determining the geographical origin of the samples. These findings provide empirical support for the combined use of elementomics and chemometric techniques in black pepper authentication, contributing to fraud prevention. The study also demonstrates the potential of the method for application to other food types.<h3>2. Metrohm: Milk powder analysis by near-infrared spectroscopy</h3>Determination of moisture, fat, lactose, and protein content<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_nir_128_download_867321cfb0.pdf">Full PDF for download</a></li></ul>For milk powder producers, final product control is essential to meet strict regulatory standards, guarantee comprehensive quality assurance, ensure consistent nutritional quality, and extend shelf life. These are all especially important for infant formula and dairy ingredients used in sensitive applications. Near-infrared spectroscopy (NIRS) is a fast, reagentfree method for measuring key quality parameters such as moisture, protein, lactose, and fat content directly in milk powder. The NIRS solution requires no sample preparation, enabling real-time monitoring either in the lab or directly on the production line. This allows producers to react quickly to process variations, minimize waste, and maintain product integrity batch after batch.<h4>EXPERIMENTAL EQUIPMENT&nbsp;</h4>More than 600 samples of powdered milk from different suppliers were analyzed on an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=56&amp;search=OMNIS+NIR">OMNIS NIR Analyzer</a> (Figure 1). The different milk powders were placed into an OMNIS sample cup and analyzed in diffuse reflection mode. To include sample variety, the sample rotated during measurement to collect spectra from different locations. The automatically averaged spectra were used for model development. Reference values were obtained by official methods, e.g., AOAC 927.05 (moisture), AOAC 939.02 (protein), and AOAC 932.06 (fat). For the lactose content determination, a phenol-sulfuric acid method was used.<h4>CONCLUSION</h4>This Application Note presented the analysis of milk powder using NIR spectroscopy. Models for several quality parameters (fat, protein, lactose, and moisture content) were created. Independent validation samples confirmed the robustness and reliability of the models, with high correlation coefficients and low prediction errors achieved across all parameters. Notably, the dataset included samples from diverse global origins, capturing a broad range of product variability. This study shows that NIRS can be successfully integrated into the quality control workflow for dairy powder analysis.<h3>3. Shimadzu: Analysis of Electrolyte and Electrode in LIB Degraded by Overcharge and High Temperature</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01064_en_b4f9f4330a.pdf">Full PDF for download</a></li></ul><h4>User Benefits</h4><ul><li>ICP-AES enables accurate quantification of cathode material dissolved in electrolytes.</li><li>GC-MS assesses degradation from components in electrolytes with unknown usage.</li><li>EDXRF easily evaluates transition metals, phosphorus, fluorine, and other elements deposited on electrodes</li></ul>When lithium-ion batteries are used in EVs or ESS applications, numerous cells are connected in series and parallel to form modules, and multiple modules are further connected to construct a pack. In such configurations—where many cells are connected in series—the state of charge of individual cells varies, as shown in Figure 1. Moreover, because the cells are densely packed to reduce volume, the ambient temperature experienced by each cell also varies. In this application, we conducted cycle tests under overcharged or high-temperature conditions, disassembled the degraded pouch cells, and analyzed both the electrolytes and the electrodes.<h4>Analysis of electrolyte and electrode</h4>Electrolytes and electrodes were extracted from the batteries degraded through the cycle tests (hereafter referred to as “degraded cells”) and analyzed using the instruments shown in Figures 3–5. It is known that electrolytesin degraded cells contain transition metals (Ni, Co, Mn) dissolved from the cathode active material1). In addition, electrolyte solvents are known to generate characteristic degradation products as deterioration progresses2). By analyzing these degradation-related elements and compounds, the degradation state of the battery can be assessed. In this article, we propose a multifaceted evaluation of electrolytes using <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=3&amp;search=ICPE-9820">ICP-AES</a> and GC-MS. On both the cathode and anode, insulating layers known as CEI/SEI form on the electrode surfaces. Under improper charging conditions, excessive formation of these layers can lead to capacity loss. Furthermore, the dissolved metals from the cathode deposit and precipitate on the anode. These deposits can cause internal short circuits, posing risks such as fire hazards. While such electrode conditions are typically evaluated by ICP-AES or XPS to examine elemental content or surface chemical states, this article introduces a simpler evaluation method using <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=3&amp;search=EDX-8100">EDXRF</a>.<h4>Summary</h4>Analysis of the electrolytesfrom degraded batteries using ICP-AES and GC-MS revealed dissolution of transition metals as well as the formation of degradation products. Furthermore, EDXRF analysis of the electrodes enabled straightforward detection of changesin elemental composition, including transition metals, fluorine, and phosphorus. These analytical techniques allow for a multifaceted evaluation of battery degradation. In real-world battery operation, fluctuations in charging conditions and ambient temperature introduce variability in degradation states. By assessing degradation mechanisms individually, as demonstrated in thisreport, it is possible to obtain insights that contribute not only to improving intrinsic battery performance but also to optimizing implementation methods and control conditions.<h3>4. Thermo Fisher Scientific: Analyzing Spinel refractory MgO-Al2O3 premix using <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=2&amp;search=ARL%E2%84%A2+X%E2%80%99TRA+Companion">ARL X’TRA Companion XRD</a></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/spinel_refractory_xrd_an41525_en_75f2527e78.pdf">Full PDF for download</a></li></ul>Spinel refractories—primarily magnesia–alumina (MgAl₂O₄)— are the workhorses of high-temperature linings in steel ladles, cement rotary kilns, glass tanks, and non-ferrous smelters. Their appeal lies in a combination of shock resistance, chemical stability against basic slags, and an expansion behavior that mitigates cracking. Depending on the duty, they are used as bricks, castables, or gunned repairs, sometimes with engineered microstructures that blend spinel with periclase, corundum, or zirconia to tune creep, corrosion, and spalling performance.&nbsp;X-ray diffraction (XRD) underpins manufacturing control from raw mix to fired product. During synthesis, XRD tracks the solid-state reaction of MgO and Al₂O₃ into spinel, verifying the disappearance of periclase and alumina and quantifying the spinel fraction by Rietveld analysis. Lattice parameters reveal cation stoichiometry and solid-solution effects; peak breadth trends indicate crystallite growth and microstrain, proxies for sintering progress. In finished components, XRD detects secondary phases such as calcium aluminates introduced by binders, slags, impurities, and it provides fingerprinting for batch-to-batch consistency after thermal exposure. Embedded into routine QA/QC, XRD shortens feedback loops, stabilizes recipes, and links processing conditions to the microstructure that governs refractory life.<h4>Instrument &amp; software&nbsp;</h4>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=2&amp;search=ARL%E2%84%A2+X%E2%80%99TRA+Companion">Thermo Scientific™ ARL™ X’TRA Companion</a> X-Ray Diffractometer (c.f. Figure 1) is a simple, easy-to-use benchtop instrument for routine phase analysis as well as more advanced applications. The ARL X’TRA Companion uses a θ/θ goniometer (160 mm radius) in Bragg-Brentano geometry coupled with a 600 W X-ray source (Cu or Co). The radial and axial collimation of the beam is controlled by divergence and Soller slits, while air scattering is reduced by a variable beam knife. An integrated water chiller is available as an option. Thanks to the state-of-the art solid state pixel detector (55x55 μm pitch), the ARL X’TRA Companion provides very fast data collection and comes with single-click Rietveld quantification capabilities and automated result transmission to a LIMS (Laboratory Information Management System) seamless integrated into Thermo Scientific™ SolstiX™ Pronto instrument control software.<h4>Your benefits&nbsp;</h4>The ARL X’TRA Companion XRD workflow delivers answers in minutes, quantifying MgO, α-Al₂O₃, and MgAl₂O₄ while resolving Ca–Si silicates and trace Fe-spinels. Subtle differences between corundum and spinel are cleanly separated, and LOI drivers—carbonates, brucite, and Mg-sulfates—are identified and trended. These insights let you compute spinel potential, anticipate pore-closing expansion, and set the right pre-dry / prefire schedule to avoid spalling. You can clearly distinguish mid-grade, ore-derived feeds from premium low-silica materials, tighten incoming QA, and optimize formulations for cement/lime kilns, tundish linings, and other carbon-free basic applications.

Agilent Technologies: Routine Analysis of Rare Earth Elements in Basalt using ICP-MS</h3>Accurate, precise, and stable results in a basalt sample matrix with the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=7850+ICP-MS">Agilent 7850 ICP-MS</a> in helium collision mode&nbsp;<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_rare_earth_metals_7850_icp_ms_5994_8963en_agilent_07d5eb637c.pdf">Full PDF for download</a></li></ul>Rare Earth Elements (REEs) play a vital role in numerous industrial applications, including advanced materials, electronics, renewable energy technologies, and geochemical research.1 Precise and routine quantification of REEs in geological matrices such as basalt is essential for understanding magmatic processes, resource assessment, and environmental monitoring. ICP-MS is suitable for the analysis of trace REEs in basalt. However, the sample poses significant analytical challenges due to its complex matrix, high concentrations of major elements, and the risk of polyatomic interferences such as oxides and hydroxides of barium (Ba) and REEs that can compromise accuracy.1–3 Because it contains high levels of alumina, silica, and refractory metals, basalt can also compromise plasma robustness due to matrix-induced signal suppression.Various techniques have been used to measure REEs in geological samples, including multicollector (MC-) ICP-MS detection following α-hydroxyisobutyric acid (HIBA) separation.4 Instrumental Neutron Activation Analysis (INAA) offers excellent sensitivity for many lanthanides (and long lived actinides like thorium and uranium) but is constrained by long irradiation times and the need to access nuclear reactors.5 Thermal Ionization Mass Spectrometry (TIMS) provides highly precise isotopic measurements; however, it requires complex sample preparation and is unsuitable for routine multi-element analysis.6 Laser Ablation ICP-MS (LA-ICP-MS) enables direct, spatially resolved measurements of geological samples but demands careful matrix matching of standards and is sensitive to variations in ablation behavior.7 High-Resolution ICP-MS (HR-ICP-MS) improves spectral resolution, yet its high cost, lower throughput, and operational complexity limit its widespread use. While these techniques remain valuable for specialized applications, they often fall short when laboratories require rapid, routine, and interference-free determination of lanthanides and actinides in rock matrices.&nbsp;ICP-MS has become the preferred technique for routine REE analysis due to its exceptional sensitivity, wide linear dynamic range, and multi-element capability. In this study, REE measurements were performed using an Agilent 7850 ICP-MS with an Agilent SPS 4 autosampler and controlled using Agilent ICP-MS MassHunter software. A preset method enabled the accurate and precise determination of 16 lanthanide and actinide elements in a single run, supporting high sample throughput. The 7850 includes Octopole Reaction System (ORS⁴) cell technology and optimized helium (He) collision mode to effectively remove polyatomic ion interferences using Kinetic Energy Discrimination (KED). Common interferences can be eliminated by the 7850 using default He KED tuning conditions, ensuring reliable analysis in complex matrices.8,9 As polyatomic ions pass through the ORS⁴ cell with an optimized helium flow, their larger collisional cross sections cause them to lose more kinetic energy via frequent collisions. Upon exiting the cell, these lower energy polyatomic ions are filtered out by the KED barrier, while analyte ions retain enough energy to pass through the quadrupole for detection by the electron multiplier detector. This process enables accurate multi element analysis using a single gas mode.<h4>Experimental&nbsp;</h4><h5>Instrumentation&nbsp;</h5>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=7850+ICP-MS">Agilent 7850 ICP-MS</a> equipped with the ORS4 cell and an Agilent SPS 4 autosampler was used for all the measurements of the basalt sample. (The same 7850 ICP-MS setup is also installed at Geochemistry and Geochronology facility of the Institute of Seismological Research, India.) Because ammonium fluoride (NH4 F) was used during sample preparation, the 7850 ICP-MS was fitted with the optional PFA kit and platinum sampling and skimmer cones. All 16 elements were measured using one set of He KED collision cell mode conditions. He KED ensures effective control of most background and matrix-based polyatomic interferences, such as ArO, ArCl, and BaO. The instrument was controlled using ICP-MS MassHunter software. Typical instrument operating parameters are listed in Table 1. The highlighted parameters were predefined by selecting the General Purpose preset method, while lens voltages were automatically tuned for optimal performance using the software’s autotune feature.<h4>Conclusion&nbsp;</h4>The Agilent 7850 ICP-MS successfully quantified all 16 lanthanides and actinide elements in the basalt CRM using a single helium KED cell method. The use of a General Purpose preset method and automated lens tuning routine within the Agilent ICP-MS MassHunter software streamlined the analytical workflow, minimizing instrument setup time and ensuring consistent instrument performance. These ease of use features simplified instrument operation while maintaining accurate, interference free results. Internal standard stability over three hours of continuous operation demonstrated the robustness of the 7850 under routine, high throughput conditions. This level of instrument stability is important for maintaining productivity, as it reduces drift, QC failures, sample reanalysis, and instrument maintenance. The 7850 ICP-MS method supports laboratories conducting routine, high-throughput multi-element analyses of demanding geological matrices.<h3>2. Metrohm: Flour analysis by near-infrared spectroscopy (NIRS)</h3>NIR flour analysis determines moisture, protein, ash, gluten, starch, and rheological properties within seconds<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_nir_123_download_f35ec480b3.pdf">Full PDF for download</a></li></ul>Monitoring ash content, along with key quality parameters such as protein and moisture content, can significantly enhance the milling yield of flour. Next to these chemical parameters, rheological parameters like baking strength or tenacity influence the product quality. Near-infrared (NIR) spectroscopy enables chemical-free quality control of both chemical and rheological parameters, producing results within seconds. This simple, efficient, and rapid analysis method is ideal for continuous quality checks and can be implemented in laboratory settings or atline, requiring minimal training for effective use.<h4>EXPERIMENTAL EQUIPMENT&nbsp;</h4>A total of 237 flour samples, including wheat flour, spelt flour, and other types, were analyzed on a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=220&amp;search=omnis+nir">Metrohm OMNIS NIR Analyzer Solid</a> (Figure 1) with the large cup OMNIS NIR, 100 mm and OMNIS software. The samples were filled into the sample cup and analyzed in diffuse reflection mode. To include sample variety, the sample cup rotated during measurement to collect spectra from different locations. The automatically averaged spectra were used for model development. Reference values for moisture, protein, and ash content were obtained with the respective primary methods: moisture analysis followed AOAC 953.10, protein according to AOAC 2001.11, and ash content followed AOAC 923.03.<h4>CONCLUSION</h4>This Application Note shows the feasibility of using NIR spectroscopy for the analysis of several quality parameters in flour. With no chemicals involved, nearinfrared spectroscopy is an ideal way to avoid timeconsuming sample preparation and reduce costs. NIRS instruments from Metrohm allow users to not only to monitor the flour milling process, but also to predict the rheological properties of the dough the flour is produced with.<h3>3. Shimadzu: Observation of Expansion/Contraction Process of Bubbles in PVA Gel</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_00855_en_d5da0bf713.pdf">Full PDF for download</a></li></ul><h4>User Benefits</h4><ul><li>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=HPV-X3">HPV-X3</a>, with a maximum framerate of 20 Mfps, is suitable for observation of high-speed phenomena such as cavitation.</li><li>The HPV-X3 provides 3 times higher resolution than the conventional device, enabling detailed observation.</li><li>Since the image sensor of HPV-X3 is burst-type, the HPV-X3 enables image acquisition with constant resolution, regardless of the recording speed.</li></ul>When laser-induced shock waves and cavitation are applied in the medical field, it isimportant to understand the actual phenomena. Here, a polyvinyl alcohol (PVA) gel was irradiated with a laser, and the condition of the shock wave and cavitation generated upon laser light condensation (LC) was observed. PVA gel has high biocompatibility and is known as a promising biomaterial which is suitable for tissue mimicking. In this experiment, the newlydeveloped Hyper Vision HPV-X3 high-speed video camera was used to observe bubble expansion/contraction in PVA gel. In comparison with the conventional device, the recording speed (framerate) of the HPV-X3 is 2 times faster. The new HPV-X3 also provides 3 times higher resolution, supporting more detailed observation.<h4>Comparison of HPV-X3 and HPV-X2</h4>Fig. 2 shows images captured by the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=HPV-X3">HPV-X3</a> and <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=HPV-X2">HPV-X2</a>. The images show the condition of the bubble and shock wave after laser irradiation captured at 500 kfps (HP mode of HPV-X2). As can be seen in Fig. 2 (a) and (b), assuming the same device composition, the HPV-X3 can capture a wider field due to its larger sensor size. In Fig. 2 (c), the image has been partially cropped from Fig. 2 (b) to show the same field of view as the HPV-X2. It can be understood that the information in the cropped image is also clearer due to the three-fold improvement of the resolution of the HPV-X3. Thus, when a wide field of view is captured in order to check the phenomena and the image is then cropped to show only the phenomenon of interest, the HPV-X3 is the more suitable device thanks to its excellent resolution.<h4>Conclusion&nbsp;</h4>Hyper Vision and HPV are trademarks of Shimadzu Corporation or its affiliated companies in Japan and/or other countries. Using the new HPV-X3 high-speed video camera, the expansion/contraction of a bubble and shock wave when a laser was irradiated on PVA gel were observed. Because the resolution of the HPV-X3 is 3 times higher than that of the conventional device, resolution is adequate, and it is possible to obtain clear and distinct images, even when a wide angle of view is observed and the image is partially cropped. The HPV-X3 also has a maximum recording speed of 20 Mfps, which enabled detailed observation of the shock wave and the process of bubble collapse.<h3>4. Thermo Fisher Scientific: Analysis of rare earth elements in clay using XRF and XRD</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/analysis_of_rare_earth_elements_an41526_en_df78e144e1.pdf">Full PDF for download</a></li></ul>Rare earth elements (REEs) are 17 elements used in dozens of high-tech applications. The global demand for REEs has surged in recent years, driven by advancements in technology and the transition towards green energy solutions. REE magnets are compact, efficient, and hard to replace. Electric vehicles (EVs) and wind power are the main growth industries for these use cases.&nbsp;Although rare earth elements are relatively abundant in the earth’s crust, they are rarely concentrated into mineable ore deposits. REEs are associated with alkaline rocks, carbonatite (bastnäsite, monazite, parisite, and synchysite), pegmatite, and placer deposits (residual deposits formed from deep weathering) and are often discovered via geochemical exploration. They may also be absorbed in clay minerals or ion adsorption clays (IACs) such as kaolinite, illite and smectite. The ores of rare earth elements are mineralogically and chemically complex and commonly radioactive. REE mining is challenging because REEs are concentrated in more than one mineral, and each mineral requires a different costly extraction technology and mineral processing.&nbsp;For companies operating in REE exploration and mining, the accuracy of geochemical analysis is critical to assess the viability of deposits, respectively targeting REE rich areas for extraction. The Thermo Scientific™ ARL™ X’TRA Companion X-ray Diffractometer detects and quantifies mineral phases that contain REEs such as kaolinite, smectite, monazite and bastnasite. Thermo Scientific™ ARL™ PERFORM’X WDXRF Spectrometer on the other hand provides fast, accurate major/minor oxides analysis on the REE ores.<h4>Instrument and software&nbsp;</h4>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2296">ARL X’TRA Companion X-Ray Diffractometer</a> (Figure 1) is a simple, easy-to-use benchtop instrument for routine phase analysis as well as more advanced applications.

The radial and axial collimation of the beam is controlled by divergence and Soller slits, while air scattering is reduced by a variable beam knife. An integrated water chiller is available as an option. Thanks to the state-of-the art solid state pixel detector (55x55 μm pitch), the ARL X’TRA Companion XRD provides very fast data collection and comes with single-click Rietveld quantification capabilities and automated result transmission to a LIMS (Laboratory Information Management System). Both capabilities are seamlessly integrated into <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2297">Thermo Scientific™ SolstiX™ Pronto Instrument Control Software</a>.&nbsp;The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1211">ARL PERFORM’X series spectrometer</a> (Figure 2) used in this analysis was a 2500-watt system. This system is configured with 6 primary beam filters, 4 collimators, up to nine crystals, two detectors and our 5GN+ Rh X-ray tube for best performance from ultra- light to heaviest elements thanks to its 50 microns Be window. This innovative, ultralight X-ray tube fitted with a low current filament ensures an unequalled analytical stability month after month. When paired with industry-leading Thermo Scientific™ UniQuant™ Software the ARL PERFORM’X spectrometer provides the best limits of detection and accuracy in standardless analysis up to element Am.<h4>Your benefits&nbsp;</h4>The ARL X’TRA Companion XRD workflow delivers answers in a few minutes, quantifying the mineral phases available in the ion adsorption clay samples. Users are able to identify the type of mineral phases associated with REEs such as kaolinite, halloysite, smectite, illite. They are also able to verify the ion adsorption clay (IAC) mechanism due to absence of monazite/ xenotime peaks &amp; availability of kaolinite &amp; smectite which supports ion-adsorbed REE.&nbsp;ARL PERFORM’X WDXRF spectrometer together with UniQuant standardless analysis software enables the users to screen through REE ores for up to 79 elements without the need for conventional calibrations. Well suited for mining ore analysis which will have varying sample matrices. UniQuant software is fully calibrated and installed from the factory. Hence the ARL PERFORM’X spectrometer is ready to perform meaningful analysis of unknown samples directly after installation at the customer’s site.
