Agilent Technologies: Measurement of Opaque Liquids with UV-Vis and ATR</h3>Combining the Agilent Cary 60 UV-Vis spectrophotometer with an ATR fiber-optic probe<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_cary_60_atr_opaque_liquids_5994_8652en_agilent_e7b9efab4d.pdf">Full PDF for download</a></li></ul>Today, ATR is considered synonymous with FTIR spectroscopy, being the most widely used sampling technique. However, ATR can also be applied to UV-Vis spectroscopy, offering particular benefits for measuring opaque liquids with a fiber-optic probe.&nbsp;Samples such as paints, inks, food colorings, sunscreens, and liquid medications are often highly pigmented, rendering them optically opaque. In some cases, measurement of these types of samples using a standard 10 mm path length cuvette may be possible, but only after several hundred‑fold dilution, requiring significant solvent consumption and introducing the possibility of large dilution errors. In the case of emulsion samples such as paints and sunscreens, dilution is often not possible without the sample "splitting" and separating into its component parts.&nbsp;ATR spectroscopy is an innovative sampling technique that overcomes these challenges. In ATR, incident light from the spectrometer is directed into a measurement crystal at an angle. Internal reflections within the crystal generate an evanescent wave at the crystal surface, allowing samples in direct contact with the crystal to interact with the standing wave and absorb some of the light energy.&nbsp;In a UV-Vis fiber-optic ATR probe, a commonly used crystal is sapphire, with the incident light directed into the crystal to form an angle of 60° at the crystal surface. The crystal is designed to create three bounces at the surfaces (Figure&nbsp;1). The "effective height" of the wave above the surface is a function of the relative refractive indices of the crystal and the sample medium, the angle of incidence, and the wavelength. The multiple bounces extend the effective path length. For this probe, the effective pathlength at 250&nbsp;nm is approximately 3 μm and increases to approximately 13 μm at 1,000&nbsp;nm.<h4>Experimental&nbsp;</h4>Example data were collected using a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=Cary+60+UV-Vis">Cary 60 UV-Vis spectrophotometer </a>equipped with a fiber-optic interface and Hellma Katana XP 6, 3-bounce ATR probe (Hellma part number PK1KSSZUEASM210N). Spectra were collected by first measuring a baseline using the clean crystal, followed by sample measurement with the crystal immersed in the sample. The Agilent <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=Cary+WinUV">Cary WinUV software</a> was used to collect the spectra as well as to process the measured spectra. All spectra were collected using the measurement conditions shown in Table 1.<h4>Conclusion&nbsp;</h4>This application note demonstrates how an Agilent Cary 60 UV-Vis spectrophotometer, when combined with a Hellma Katana XP 6 ATR probe, provides a practical and easy-to-use solution for measuring optically opaque liquids that would otherwise require extensive dilution, and for monitoring reactions with absorbance changes too large for conventional methods. The Cary 60 UV-Vis with the ATR probe combination is a powerful tool for a wide range of applications, including routine quality control, R&amp;D studies, and research and teaching laboratories.<h3>2. LECO: Determination of Nitrogen/Protein in Meat and Plant-Based Meat Alternatives</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/FP_828_NITROGEN_PROTEIN_MEAT_PLANT_BASED_MEAT_ALTERNATIVES_203_821_680_266d8d12f8.pdf">Full PDF for download</a></li></ul>Protein is one of the most significant nutrient components in food products. The accurate and precise determination of protein not only plays a role in the characterization of nutritional or dietary value in food materials but is also the key to the economic value of these materials. Protein in meat products is most commonly calculated using the measured nitrogen content in the sample and a multiplier or conversion factor (commonly 6.25). Nitrogen determination is performed using either the classical wet chemical method (Kjeldahl) or a combustion method (Dumas). The Kjeldahl method involves sample digestion, distillation, and ammonia determination typically by titration. This method involves time-consuming sample preparation and the use of hazardous materials. The LECO FP828 is a nitrogen determinator that utilizes an automated combustion (Dumas) method and provides accurate and precise results in approximately three minutes. This eliminates involved sample preparation and the use of hazardous materials resulting in a rapid, cost-effective method for the quality control of the production of meat and plant-based protein products.<h4>Instrument Model and Configuration&nbsp;</h4>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=24&amp;search=FP828">LECO FP828</a> is a combustion Nitrogen/Protein determinator that utilizes a pure Oxygen environment in a vertical quartz furnace, ensuring complete combustion and superior analyte recovery. A thermoelectric cooler removes moisture from the combustion gases before they are collected in a ballast. The combustion gases equilibrate and mix in the ballast before a representative aliquot (3 cm3 or 10 cm3 volume) of the gas is extracted and introduced into a flowing stream of inert gas (Helium or Argon) for analysis. The aliquot gas is carried to a thermal conductivity cell (TC) for the detection of Nitrogen (N2).Thermal conductivity detectors work by detecting changes in the thermal conductivity of the analyte gas compared to a reference/carrier gas. The greater the difference between the thermal conductivity of the carrier gas and the analyte gas, the greater sensitivity of the detector.&nbsp;The FP828 supports either the use of Helium or Argon as the instrument's carrier gas. When used as a carrier gas, Helium provides the highest sensitivity, and the best performance at the lower limit of the Nitrogen range.&nbsp;The thermal conductivity difference between Argon and Nitrogen is not as great as the thermal conductivity difference between Helium and Nitrogen, therefore the detector is inherently less sensitive when using Argon as a carrier gas.<h4>TYPICAL RESULTS&nbsp;</h4>Data was generated utilizing a linear, force through origin calibration using ~0.25 g of LECO 502-896 (Lot 1007) LCRM EDTA (9.59% N). The calibration † was verified using ~0.1 g of LECO 502-642 (Lot 1020) LCRM Phenylalanine (8.46% N). A protein factor of 6.25 was used for all samples to calculate the protein content.<h3>3. Shimadzu: Analysis of Combustion Ash from Biomass Power Generation by EDXRF</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_00716_en_9995b70230.pdf">Full PDF for download</a></li></ul><h4>User Benefits</h4><ul><li>EDXRF enables analysis of Na and K, which cause fluidization problems (agglomeration) in circulating fluidized bed boilers in biomass power generation.</li><li>Simple qualitative/quantitative analysis of elements is possible with minimal sample preparation.</li><li>Comparative analysis of heterogeneous samples in the as-received condition and in the homogenized condition after crushing is possible.</li></ul>In biomass power generation, electricity is generated by using bioresources (biomass) derived from animal and plant sources as a carbon neutral fuel. Biomass power is expected to contribute to reducing total CO2 emissions, and in recent years, the number of woody biomass power plants using wood chips, pellets, and palm kernelshells(PKS) hasincreased. Circulating fluidized bed (CFB) boilers used in woody biomass power generation generate power by circulating and burning biomass fuel together with silica sand, which is as a fluidized bed medium. However, alkali metal elements (Na, K) contained in the fuel adhere to the surface of the silica sand and combustion ash, causing the particles to stick together and form agglomerates (lumps, coarse particles), which are considered to cause boiler damage and fluidization problems (agglomeration) in the fluidized bed 1) .&nbsp;In this article, a Qual-Quant analysis of PKS combustion ash and its coarse particles was conducted using an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=EDX-8100">EDX-8100</a> energy dispersive X-ray fluorescence spectrometer (EDXRF). Since adhesion of alkali metal elements was detected on the surface of agglomerated lumps, which are considered to cause the problem of agglomeration, analysis of combustion ash by EDXRF can contribute to operational management of combustion furnaces by monitoring the conditionsin the combustion furnace.<h4>Conclusion&nbsp;</h4>Based on the results of a qualitative analysis of lumps (coarse particles of bottom ash), which are thought to cause agglomeration (defluidization) of the fluidized bed, in the combustion ash of PKS, it was found that alkali metal elements (Na and K) had adhered to the surface of the particles. Since EDXRF enables Qual-Quant analysis of elements with only simple sample preparation, it is considered a useful technique for monitoring the progress of agglomeration and deterioration of the silica sand in the power generation using PKS or woody biomass. Periodic measurements by EDXRF can also be expected to prevent damage and deterioration in combustion furnaces and equipmentstops due to defluidization.

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.
