An international research team, which included scientists from the Faculty of Science at Palacký University and the Institute of Physics of the Czech Academy of Sciences, has succeeded in unraveling the complex mechanism by which a chemical bond is formed during a collision between molecules. The experts found that the reaction only takes place if the molecules are oriented towards each other within a very narrow range of angles – within the so-called cone of reaction. This joint research has thus provided an answer to one of the fundamental questions of chemistry: under what conditions do chemical bonds form between molecules. The results of the study&nbsp;Spatially resolving the cone of reaction for a single molecule&nbsp;were published in the prestigious scientific journal&nbsp;Science.Many chemical reactions begin with the collision of two particles. However, for a new chemical bond to form, it is not enough for the molecules simply to come into contact. Their collision must occur with sufficient energy, in the correct relative orientation and at the right location. Under normal conditions, such as in solutions or gases, molecules collide chaotically, and the precise parameters of these collisions cannot therefore be controlled.<h4>Molecules under control</h4>Scientists were able to control the collisions of individual molecules on a copper surface and monitored the process using a scanning tunnelling microscope. They used the instrument not only to visualise individual molecules, but also to deliberately accelerate the reactants towards one another. They subsequently analysed each collision with atomic-level resolution. This enabled them to determine unequivocally whether a new chemical bond had formed between the molecules.<h5>“What is hidden in the statistics of billions of collisions in conventional chemistry, we have managed to break down into individual cases and map directly.” Adam Matěj</h5>A key finding of the study is that the outcome of a collision is determined by the extremely precise orientation of the molecules. A new bond was formed only when the target molecule was oriented within a few degrees of the direction of movement of the other molecule. When rotated by more than fifteen degrees, the molecules simply bounced off each other without any reaction.<h4>The precise orientation of the molecules is crucial</h4>“For the first time, we were able to observe, using a single molecule, exactly how precisely it must be oriented for the reaction to take place at all. What is hidden in the statistics of billions of collisions in conventional chemistry, we have managed to break down into individual cases and map directly,” said Adam Matěj from the Department of Physical Chemistry at the Faculty of Science.The theoretical part of the study, in which researchers from Palacký University and the Institute of Physics of the Czech Academy of Sciences were involved, played a significant role. Using quantum-mechanical calculations, they explained why the ‘reaction cone’ is so narrow. It turned out that the reactive carbon atom is surrounded by hydrogen atoms, which block the access of the reacting molecule from almost all directions.<h4>The arrangement of atoms restricts access to the reaction</h4>The calculations also shed light on a surprising experimental result. The chemical reaction took place even when the molecule moved along an adjacent row of copper atoms, where, according to the original assumptions, no bond should have formed.<h5>“The strength of this work lies in the fact that the experiment and theory have been brought together into a single picture. The microscope showed what happens during the collision, and the calculations explained why.” Pavel Jelínek</h5>“The explanation lies in the slight displacement of a single copper atom on the surface. The target’s bond to the surface pulls it out of its position and brings it close enough to the neighbouring row that it can literally take over the projectile and direct it to the correct spot. This shows that the surface is not merely a passive substrate, but actively participates in the reaction itself and can even facilitate pathways that would otherwise be unfavourable,” noted Adam Matěj.<h4>The surface also determines the course of the reaction</h4>The results are significant for the development of so-called surface reactions, in which new materials and nanostructures are purposefully assembled from individual molecules. A better understanding of the influence of the spatial arrangement of molecules will enable the design of molecular building blocks so that they bond more reliably and efficiently. This represents an important step towards the development of technologies based on the controlled construction of structures atom by atom.“The strength of this work lies in the fact that experiment and theory have been brought together into a single picture. The microscope showed what happens during the collision, and the calculations explained why. Without a theoretical model, we would have found it difficult to discover that the movement of a single surface atom is behind the unexpected course of the reaction,” added Pavel Jelínek from the Institute of Physics of the Czech Academy of Sciences.<blockquote>The study&nbsp;Spatially resolving the cone of reaction for a single molecule&nbsp;was produced in collaboration between researchers from the University of Graz, the Institute of Physics of the Czech Academy of Sciences, Palacký University in Olomouc, Charles University and Humboldt University in Berlin.</blockquote>

Agilent Technologies: Direct Analysis of Seawater Using ICP-QQQ and Integrated Advanced Valve System</h3>Fast, robust environmental analyses using an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500">Agilent 9500 ICP-QQQ</a> with AVS MS&nbsp;<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_seawater_9500_icp_qqq_5994_8988en_agilent_e56319c80a.pdf">Full PDF for download</a>&nbsp;</li></ul>Trace elements in seawater play a vital role in marine biogeochemical cycles, influencing ocean productivity, ecosystem health, and global climate regulation.1,2 Although present at extremely low concentrations, many trace elements are essential for biological processes, while others, including heavy metals, serve as indicators of contamination from industrial activities and coastal development. Accurate determination of a wide range of elements is therefore critical for environmental monitoring, oceanographic research, and regulatory compliance. EPA Method 200.8 provides a widely adopted quality control (QC) framework for trace metal analysis in natural waters.3 However, seawater’s high salinity and major components such as Na, Mg, Cl, and S create analytical challenges for conventional ICP-MS analysis, including ionization suppression and polyatomic interferences, such as ArCl+ on As, ArNa+ on Cu, SO2 + on Zn. Overcoming these issues requires advanced interference removal techniques and high sensitivity. Triple quadrupole ICP-MS (ICP-QQQ) addresses these limitations through its MS/MS configuration.Agilent ICP-MS/MS methods precisely control reaction chemistry and eliminate interferences, ensuring accurate quantification in complex saline matrices.&nbsp;The Agilent 9500 Triple Quadrupole ICP-MS with its unique Dual-Cell System (DCS) enables accurate, efficient seawater analysis using enhanced collision/reaction cell (CRC) technologies. Its performance is primarily driven by Advanced Helium Mode (AHM). This advanced collision mode delivers exceptional on-mass interference removal using a combination of Kinetic Energy Discrimination (KED) and Collision Induced Dissociation (CID), ensuring precise quantification even in highly saline and complex matrices.4 Additionally, Air cell mode enables fast, effective mass-shift reactions, adding flexibility for overcoming challenging interferences.5 By seamlessly integrating AHM with Air cell mode, the 9500 simplifies workflows and delivers reliable results for trace analysis of multiple elements in seawater.&nbsp;In this study, a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500">9500 ICP-QQQ</a> fitted with the AVS MS was used to quantify 26 elements in two seawater certified reference materials (CRMs) and a sample collected in Singapore, employing an online reverse-dilution approach. The method was assessed following the performance requirements of EPA Method 200.8.<h4>Conclusion&nbsp;</h4>Traditional seawater analysis by ICP‑MS often requires extensive sample preparation, such as dilution and matrix separation, to address high salinity and complex matrix effects. These additional steps increase both turnaround time and contamination risk. The method developed here enables direct seawater analysis using an online reverse-dilution approach, eliminating manual preparation and enabling rapid, high-throughput processing. Using the Agilent 9500 ICP-QQQ with AVS MS in online dilution mode, the workflow achieved ppt-level MDLs for 26 elements, excellent accuracy (90–110% recoveries for CRMs and spiked samples), and long-term stability across more than 130 analyses, meeting EPA Method 200.8 QC requirements.&nbsp;Key advantages of the 9500 ICP-QQQ method:&nbsp;<ul><li>Effective interference removal: Advanced gas modes (AHM and Air cell mode) controlled polyatomic species originating from the high-salinity matrices.&nbsp;</li><li>High throughput: Automated online dilution and seamless gas-switching enabled complete analysis in 140 seconds per sample.&nbsp;</li><li>Robust stability: Optimized rinse protocols ensured consistent ISTD recovery and instrument performance over a seven-hour run comprising 100 injections of undiluted seawater samples.&nbsp;</li></ul>This workflow delivers fast, reliable, and high-quality seawater analysis, making it ideal for environmental monitoring and marine research laboratories seeking maximum efficiency without compromising data integrity.<h3>2. Metrohm: Moisture and protein content in corn starch with NIR spectroscopy</h3>Easily measure the quality of corn starch in seconds with NIR<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_nir_151_download_087f0d33e0.pdf">Full PDF for download</a></li></ul>Starch is a fundamental component in candy production where it is often used as a gelling agent and thickener. The confectionery industry uses it to create products with a certain consistency, like pie fillings. It is also used in a process known as starch molding where shapes are pressed into a corn starch bed for gummy candies and similar treats. Corn starch also acts as a desiccant during the candies' drying process before reuse. Therefore, the corn starch moisture content is a very important factor to consider in this process.&nbsp;Near-infrared spectroscopy (NIRS) is a fast, chemicalfree analysis technique for the determination of moisture content and corn protein content in corn starch. The NIRS solution is easy to use and can be used either atline or in a quality control laboratory.<h4>EXPERIMENTAL EQUIPMENT&nbsp;</h4>210 samples of corn starch were measured with an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=220&amp;search=OMNIS+NIR">OMNIS NIR Analyzer Solid</a> (Figure 1). All measurements were performed in reflection mode (1000–2250 nm) using a large holder and large cup (Table 1). OMNIS Software was used for all data acquisition and prediction model development. Karl Fischer titration was used to determine the water content in corn starch, and the Kjeldahl method was used to determine its protein content.<h4>CONCLUSION</h4>This Application Note shows the feasibility of using near-infrared spectroscopy for the determination of moisture and protein content in corn starch. Compared to the conventional analysis techniques used to determine these quality parameters, NIRS saves a considerable amount of time and costs. With NIR spectroscopy, analyses can be conducted without using any chemical reagents, giving users reliable results in seconds.<h3>3. Shimadzu: Observation of Crack Propagation Process in Aluminum Alloy Specimen Using Air-Servo Microfocus X-Ray CT System</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01152_en_de411e6e13.pdf">Full PDF for download</a></li></ul><h5>User benefits</h5><ul><li>The Air-Servo Microfocus X-Ray CT System enables observation of crack propagation in three dimensions and over time.</li><li>Microfocus X-Ray CT system enables nondestructive observation of the interior of materials.</li><li>High-precision dynamic control is possible with the Servo Controller 4830.</li></ul>Many structural failures are caused by fatigue failure resulting from repeated loading. In fatigue failure, cracks initiate from microdefects in the material, internal voids, inclusions, and other features, and then propagate under repeated loading until final fracture occurs. To evaluate this sequence of processes, it is effective to observe defects and crack propagation nondestructively.&nbsp;Traditionally, crack observation has focused on visual inspection and microscopic observation, but these methods are limited to information near the surface. To sufficiently capture the threedimensional shape and changes in cracks propagating inside a material, observation of the fractured specimen after failure has generally been used. In contrast, X-ray CT can nondestructively visualize internal defects and cracks in three dimensions, making it possible to evaluate in detail changes in crack morphology, including in the interior.&nbsp;Accordingly, using the “Air-Servo Microfocus X-Ray CT System,” which combines X-ray CT with a fatigue testing machine, repeated tests were performed in which loading was stopped at fixed cycle intervals and imaging was carried out. This article introduces the resulting process of crack initiation and propagation in the same specimen.<h4>Conclusion</h4>Using the Air-Servo Microfocus X-Ray CT System, cracks propagating from the notch region of an aluminum alloy specimen were observed. First, static tests and fatigue tests were performed using the servo pulser EHF-LV, and a S-N diagram was obtained. Based on the obtained S-N diagram, the fatigue test conditions for the Air-Servo Microfocus X-Ray CT System were determined, and X-ray CT imaging was performed. The process of crack propagation according to the number of cycles was observed in cross-sectional images and 3D images. In addition, by visualizing the displacement from a specific cycle onward, it was also confirmed that the specimen necked down just before fracture.&nbsp;Using the measurement system introduced in this article, it is possible to observe changes in specimen shape over time while the specimen remains mounted in the jig. Therefore, not only the crack propagation process of a specimen during fatigue testing, but also material deformation behavior and the process of shape change can be observed.<h3>4. Thermo Fisher Scientific: IonicX Portable XRF Analyzer Device and Algorithm</h3>A detailed look into the algorithm used to authenticate ionic salts<ul><li>Other document</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/ionicx_portable_xrf_analyzer_device_and_algorithm_an1649_en_6ffee8a584.pdf">Full PDF for download</a></li></ul>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2026">Thermo Scientific™ IonicX™ Portable XRF Analyzer</a> utilizes Energy Dispersive X-ray Fluorescence (ED XRF) spectrometry to confidently differentiate between different chemical samples based on their atomic structure and the average atomic weight of the sample. The basic elements of XRF spectrometer systems include a radiation source, a sample, and an X-ray detector. The analysis relies on the interaction of radiation source output (an X-ray source) with a sample, in this case, the cup of ionic salt material, such as Sodium Chloride, Potassium Chloride, Sodium Hydroxide or other chemicals and salts. The XRF system can characterize materials, due to the fundamental principle that each element has a unique atomic structure, which in turn has a unique set of peaks (x-ray lines) in its emission spectrum. The energy dispersive X-ray detector separates (disperses) the detected radiation emitted from the sample by energy, thus providing a spectrum from which the different elements present in the sample can be identified and/ or quantified.<h4>Algorithm&nbsp;</h4>Handheld XRF devices often cannot detect elements lighter than Magnesium by their fluorescence lines, however many compounds contain elements of interest such as Oxygen and Hydrogen. Additionally, relying solely on primary fluorescence peaks to identify target compounds can lead to misinterpretation. For instance, if MgO and NaCl are present in a 1:1 mixture, the resulting XRF spectrum would display distinct characteristic Mg and Cl peaks. However, the sample would not actually be the spectrum of MgCl₂, as the analytical response of Mg and Cl would be very different in both samples because of a dilution effect and absorption from Na and O atoms. The XRF process can easily differentiate samples with similar elemental constituents but with different chemical structures by analyzing the resulting scatter from the sample and comparing the full spectrum to a calibration library of compounds. Figure 4 shows XRF spectra of Sodium Chlorate (NaClO₃) and Sodium Perchlorate (NaClO₄) taken with the IonicX XRF instrument. In this example, only the Cl fluorescence peak can be detected by the IonicX device as Na and O fluorescence X-rays have energies that are too weak to be detected. However, when the spectrum is normalized, in this case to the primary Compton peak of Ag Kα, a slight but distinguishable difference can be seen in the spectral intensity between the energies of 25 keV and 40 keV. The difference in the scatter of the X-ray tube Bremsstrahlung is caused by differences in mass absorption coefficients of the presented samples, in this case it is the extra O atom in the NaClO₄ molecule vs the NaClO₃ molecule.<h4>Summary&nbsp;</h4>The IonicX Portable XRF Analyzer is a powerful addition for the verification of ionic salt type chemicals, utilizing XRF technology in a versatile, easy to use, small form factor. IonicX provides clear, easy to understand, unambiguous results and tools to assist with compliance and data integrity. IonicX is a robust verification tool which allows pharmaceutical companies to more efficiently verify incoming chemicals that typically have been tested using lengthy wet-chemistry techniques.

Water quality is critical across many applications, including drinking water, beverage manufacturing, and wastewater. In food and beverage environments, contaminants can affect organoleptic properties, such as taste and appearance, as well as the overall safety of the water.A wide range of analytes can impact water quality, including nitrate content, and multiple methods available to assess the concentration of these components. UV-Visible spectrophotometry is one such technique, enabling the quantification of many analytes that influence water quality. As Beer’s law indicates, measured absorbance in the UV-Visible range is directly proportional to concentration, making the technique particularly useful when assessing analyte concentration.In many analyses, colorimetric reagents as required to produce a measurable absorbance in this spectral range. A standard curve is then typically developed using known standards to correlate the measured absorbance with the concentration of the analyte.In this webinar, attendees will discover how instruments such as Thermo Scientific GENESYS G5 UV-Visible spectrophotometers can support the assessment of water samples from a variety of sources.<h4>You’ll learn:</h4><ul><li>Explore different environments where water analysis can be important.</li><li>Learn how UV-Visible spectrophotometry can be used to determine the concentration of various analytes commonly assessed in water applications.</li><li>Understand best practices for using pre-built standard curves and creating new curves when determining analyte content in water sources.</li></ul><blockquote>Presenter: Jennifer Empey-Kohl (Applications Scientist, Thermo Fisher Scientific)Jennifer Empey-Kohl has been with Thermo Fisher Scientific as an Applications Scientist for 5 years where she supports the cuvette-based UV-Visible instruments.

Renewable energy resources such as solar are promising complements to the combustion of fossil fuels. However, the intermittent and diurnal nature of sunlight necessitates economical and efficient energy storage technologies. A promising approach to both storing solar energy and generating combustible liquid fuels is driving the transformation of abundant energy-poor feedstocks (CO2, H2O) into energy-dense liquid fuels using energy from solar photons, known as “artificial photosynthesis.”&nbsp;One approach for artificial photosynthesis is to immobilize fuel-producing molecular catalysts onto light-absorbing semiconductor materials to create “hybrid photoelectrodes,” allowing for both the stability of heterogenous surfaces and the tunability of molecular catalysts. The Center for Hybrid Approaches in Solar Energy to Liquid Fuels (CHASE) is a multi-institutional energy innovation hub which aims to advance hybrid photoelectrodes for the light-driven generation of liquid fuels from CO2 and H2O. A variety of chemical techniques, including sonochemical hydrosilylation, π-π stacking, and electrochemical grafting, are utilized to anchor ruthenium and rhenium molecular CO2-reduction catalysts to a silicon surface.&nbsp;To study the efficacy of these catalyst loading techniques, Inductively Coupled Plasma Mass Spectrometry (employing an Agilent 7850 ICP-MS) is leveraged to quantify catalyst surface coverage. Silicon samples are digested in an HNO3/HCl matrix to solubilize ruthenium and rhenium metal centers. As each anchored molecular catalyst contains one metal center, surface coverage estimates can be drawn by pairing ICP-MS data with the dimensions of the catalyst and the size of the silicon photoelectrode. From these data, key conclusions are drawn which correlate anchoring technique, reaction time, and silicon morphology to the loadings of these molecular catalysts. This information provides a guiding framework for next-generation designs of hybrid photoelectrodes.<blockquote>Presenter: Jillian L.

Laboratories are under growing pressure to handle increasing volumes of samples and data while operating under tighter regulatory inspection, all without compromising turnaround times or traceability. In this context, many organizations attempt to extend existing workflows and legacy tools, which can introduce inefficiencies, increase manual effort, and create compliance risks. At the same time, it is not always clear which digital solutions are best suited to address these challenges.This presentation illustrates how modern digital laboratory environments streamline routine activities by minimizing manual tasks and embedding compliance directly into everyday workflows. Drawing on a real-world use case, we show how automated capture of data from multiple sample measurements at the point of execution enables a continuous, sample-centric workflow.By removing manual interventions and paper-based processes, laboratories can improve efficiency and visibility, support faster and more reliable decision-making while remaining responsive to evolving customer demands.<h4>Learning Points</h4><ul><li>The role of different systems (LIMS, SDMS, ELN) within the digital lab landscape and how they differ from each other's</li><li>How WebLab manages laboratory operations from a sample perspective, enabling you to track every sample, stage, and next action across workflows</li><li>How automated data capture from connected instruments helps reduce errors, lower contamination risks, and accelerate sample processing</li><li>You will see, through a real-life example, how integrated digital workflows improve data quality, accelerate reporting, and increase operational efficiency</li></ul><h4>Who should attend</h4>Professionals working in small to mid‑sized laboratories, including:<ul><li>Directors and Managers of Analytical, QC, or Contract Labs</li><li>Lab Operations and QA/QC Leaders</li><li>Digitalization and IT at organizations transitioning from paper, Excel, or legacy systems to LIMS</li></ul><blockquote>Presenter: Peter Bellstedt, PhD (Director of Business Development and Product Manager at SciY)Peter studied Biochemistry at the University of Jena before completing a PhD on the structural characterization of a DNA repair protein using solution and solid-state NMR.

An accessory to make absolute specular measurements for specific angles has been available for decades. It's limitation is that it is not easily adaptable to measuring absolute reflectance at any given angle. The Cary 7000 with its unique accessory design has changed the difficulty of the measurement from being a limitation to one of ease. Adding the desire to measure both reflectance and transmission at the same angle increases the design problem which previously was dealt with by using two accessories, one for reflectance and one for transmission. This approach led to uncertainties in knowing the measurements were being made on the same spot. This presentation will look at the design of an absolute reflectance accessory along with the ease of use to be able to collect absolute specular measurements at nearly any user desired angles.<blockquote>Presenter: Scott Melis, PhD (Application Scientist, Agilent Technologies, Inc.)Scott Melis has a PHD in Physics from Georgetown University in Washington, DC and started with Agilent in 2021 as a Molecular Spectroscopy Application Scientist. In his graduate work, Scott studied nanoparticle formation and growth for a variety of applications.

Understanding the tissue microenvironment in tumour samples is an important factor for predicting response to different treatment regimens. Highly multiplexed imaging of tenfolds of protein markers can help to define this complex biology. However, these assays are costly and not always easy to scale for larger translational studies that are often needed to translate findings to clinical evidence.&nbsp;In this webinar, we demonstrate how we move from a highly multiplexed imaging platform used in a discovery phase to identify a marker for response prediction to immunotherapy at the translational phase. This transition was possible with the use of the Invitrogen™ EVOS™ S1000 Spatial Imaging System in combination with the Invitrogen™ Aluora™ Spatial Amplification Kits and a panel of 6 markers. By focusing on the most relevant targets from the discovery panel, the cost per sample is reduced to about 25 % of the initial assay, thereby resulting in a more affordable option for larger translational cohort studies. In addition, we show how relevant protein markers can be combined with in situ proximity Ligation Assay (is PLA) to simultaneously look at protein interactions, in this case demonstrated for PD-1/PD-L1. In summary, this workflow enables scalable, cost-effective spatial biology approaches that bridge discovery and clinical translation.&nbsp;<h4>Learning Objectives:</h4><ul><li>Learn how to transition from discovery to translational proteomic imaging assays&nbsp;</li><li>Understand how spectral imaging with the EVOS S1000 Spatial Imaging System can be used for hypothesis-driven research</li><li>Explore the use of spatial amplification reagents for exploring the tissue microenvironment</li></ul><blockquote>Presenter: Charlotte Stadler, PhD (Co-director of Spatial Biology and Head of the National Spatial Proteomics facility at Science for Life Laboratory)Charlotte Stadler is the co-director of the Spatial Biology platform and Head of the National Spatial Proteomics facility at Science for Life Laboratory.
