Shimadzu: High-Speed Measurement of Microplastics Smaller than 100 μm Collected on a Filter and Efficient Analysis&nbsp;</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_00994_en_936f28e894.pdf">Full PDF for download</a></li></ul><h5>User Benefits</h5><ul><li>It enables high-speed measurements of microplastics (MPs) smaller than 100 µm that are collected on a filter.</li><li>Particle analysis program can identify the types of MPs and easily analyze color-coded by type and counting the number of MPs.</li><li>In addition to calculating the size of MPs (minor axis, major axis, Feret diameter, and area), it can also estimate the volumes and masses of particles</li></ul>Microplastics (MPs) with diameters ranging from a few µm to 5 mm are widely recognized as an environmental problem in marine environments, and reports of MPs smaller than 100 µm in drinking water are attracting particular attention. 1) To confirm the number and shape of MPs smaller than 100 µm and qualitatively analyze them, samples are usually collected on a filter and observed and measured using an infrared or Raman microscope. For that process, mapping measurements of a specified area is simpler than searching for candidate MPs on the filter and performing point measurements, and it reduces the risk of overlooking particles. However, it is more timeconsuming, and it also requires analyzing the MPs after they are measured to identify the candidates, determine their sizes, aggregate the data, and so on. Therefore, a High-Speed mapping program and particle analysis program were developed to reduce the time required for these measurement and data analysis steps. In this example, High-Speed mapping was used to measure a standard MPs sample, and the particle analysis program was used to analyze the distribution of MPs within the sample.<h4>Measurement Conditions and High-Speed Mapping Program</h4>Measurement conditions are listed in Table 1. Mapping measurements are especially useful for measuring samples with many of target objects in the field of view. Normally, they take longer for larger measurement areas or larger numbers of measurement points, but that can be shortened with the HighSpeed mapping program.&nbsp;The program detects peaks based on data from the first scan at each measurement point and the specified noise level and threshold value settings. If no peak is confirmed, the program moves to the next measurement point. (If a peak is confirmed, the same number of measurements is performed as the number of scans specified.)&nbsp;In this example, a peak detection range of 3,200 to 2,800 cm-1 was specified for detecting the signal from hydrocarbons (C-H), and the data from peaks in that range were scanned the specified number of times.<ul><li>Instruments: <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=IRTracer-100">IRTracer-100</a>, AIMsight PF Holder (13 mm dia.)</li></ul><h4>Conclusion&nbsp;</h4>MPs that were collected on a filter were measured using an infrared microscope and the High-Speed mapping program. Because the High-Speed mapping functionality can measure locations in which only candidate MPs are present, samples can be measured faster than with regular mapping methods.&nbsp;And with the particle analysis program, candidate MPs can be specified as components to be analyzed, so particle counts and size distributions within measurement areas can be easily determined. This example also showed that the volume and mass of particles can be estimated.&nbsp;Counting MPs smaller than 100 µm while qualitatively analyzing the particles requires an instrument like an infrared microscope, which enables the High-Speed mapping program or particle analysis program to analyze MPs and MPs data more smoothly.<h3>4. Thermo Fisher Scientific: Rolling over interferences: How triple quadrupole ICP-MS facilitates the analysis of challenging samples for electric vehicles&nbsp;</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/po_001857_tea_electric_icp_ms_ewcps_po001857_em_en_4b2a2ed6a7.pdf">Full PDF for download</a></li></ul>The continuous development of lithium-ion battery technology is a key step to move away from the combustion of fossil fuels at point of use. Lithium based batteries are the most promising, as they provide high capacity, good cycle stability, at moderate cost. To achieve the intended performance, it is of high importance to assure consistent quality and especially purity of the raw materials used. This includes specifically the cathode material (like binary or ternary alloys containing lithium, cobalt, manganese and nickel) and the electrolyte (lithium hexafluorophosphate and organic compounds), but also other components of the battery. This presentation will provide an overview of how triple quadrupole ICP-MS is able to resolve the analytical challenges encountered when analyzing battery material samples. The presentation will include examples from different components of a battery, including raw materials, electrolytes and cathode materials.<h4>Materials and methods</h4><h5>Instrumentation&nbsp;</h5>A <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1206">Thermo Scientific™ iCAP™ TQe ICP-MS system</a> was used for all analyses. To facilitate the direct analysis of highly concentrated solutions, as typically found when working with cathode materials, the instrument was operated using Argon Gas Dilution (AGD) to automatically dilute the sample aerosol using a clean stream of argon gas, delivered directly from the instrument.&nbsp;To achieve the best possible detection limits on typically challenging elements, a slightly different configuration was applied to the same instrument. For these measurements, the instrument was equipped with a PLUS torch, a direct replacement for the standard torch made from a high purity ceramic material. The PLUS torch helps to reduce the backgrounds typically observed for silicon when using quartz torches and is therefore instrumental in achieving the best possible detection limits for this element.<h5>Data Analysis&nbsp;</h5><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1489">Thermo Scientific™ Qtegra™ Intelligent Scientific Data Solution Software</a> was used to operate the instrument and all peripherals, acquire the data and evaluate the results.&nbsp;<h4>Conclusions&nbsp;</h4><ul><li>The use of triple quadrupole ICP-MS and oxygen as a reactive gas provided the advanced performance required for the accurate determination of critical elements, such as arsenic and selenium free from polyatomic interference in a highly complex lithium battery matrix samples showing outstanding analysis performance.&nbsp;</li><li>Triple quadrupole ICP-MS in combination with oxygen as a reactive cell gas is a powerful tool for the analysis of elements having high ionization potentials and numerous spectral interferences.&nbsp;</li><li>Further reduction of the background for silicon is possible when using the PLUS torch, so that significant improvements of the detection limits for silicon can be achieved.</li></ul>

Shimadzu: Analyzing Microscopic Contaminants Embedded in Recycled Plastic</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01001_en_79904665ce.pdf">Full PDF for download</a></li></ul>Reusing plastic waste is key to achieving a carbon-neutral society, which is why targets have been established for levels of recycled plastic in plastic products. But quality control of recycled plasticsis essential for maintaining the functional properties of plastic productssince impropersorting, transporting, and processing can all lead to contamination of recycled plastic. Determining the type and quantity of contaminants in recycled plastic is important since they can have a significant negative impact on product performance in certain applications.&nbsp;Shimadzu’s infrared microscopes use high-speed mapping analysis to quickly find and characterize contaminants dispersed in recycled plastic, and Shimadzu’s particulate analysis program also provides a convenient and simple tool for determining the morphology and numbers of contaminants.&nbsp;This Application News describes using this equipment and tools to analyze contaminants in recycled plastic material that was formed into a film.<h4>High-Speed Mapping Analysis of Recycled Plastic</h4>For recycled plastic with a relatively simple infrared spectrum, contaminants embedded in the plastic can be analyzed without removing them from the plastic. This is achieved by configuring wavenumber ranges (exclusion ranges) that exclude the peaks of the recycled plastic in the settings of the high-speed mapping software. In this example, a thermal press was used to form recycled plastic composed of PE and PP into a plastic film approximately 100 µm thick. The high-speed mapping settings were then configured to detect peaks in wavenumber regions that contain hydroxyl groups and carbonyl groups that are not normally found in PE or PP. Table 1 shows the analysis conditions in detail. Background readings were obtained from an area of the film with no contaminants.<ul><li>Equipment: <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=IRTracer-100">IRTracer-100</a>, <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=AIMsight+">AIMsight</a>&nbsp;</li><li>Software: AMsolution, high-speed mapping software, particle analysis program</li></ul><h4>Conclusion&nbsp;</h4>This Application News describes a simple and rapid method for analyzing and characterizing contaminants in recycled plastic using high-speed mapping analysis with an infrared microscope and data analysis with a particle analysis program. Areas of recycled plastic with no contaminants were scanned once, whereas areas with contaminants were scanned multiple times (50). This allowed a wide area of recycled plastic to be analyzed quickly with minimal noise in the recorded infrared spectra, reducing the analysis time to around just one-fifteenth of the time needed if every part of the recycled plastic was scanned 50 times. Also, using a thermal press to form recycled plastic pellets into a film enabled the efficient characterization of large numbers of contaminants by transmission spectroscopy and the ability to calculate their numbers in the pellets.<h3>2. Thermo Fisher Scientific: Highly sensitive analysis of distillate products per ASTM Method D8110 using single quadrupole ICP-MS</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/po_highly_sensitive_astm_method_d8110_single_quadrupole_icp_ms_po_en_d7c721bc97.pdf">Full PDF for download</a></li></ul>Control of impurities in the petrochemical industry is an essential step to ensure the quality of the crude, intermediates, and finished products. In many laboratories, the analysis of crude, intermediates, and finished products, including light and middle distillates for trace elements, is accomplished using inductively coupled plasma optical emission spectrometry (ICP-OES) or inductively coupled plasma mass spectrometry (ICP-MS). However, the regulations and specifications for content of elemental impurities are becoming more stringent, which enforces determination of these impurities at lower concentration levels. Due to its higher sensitivity and specificity, ICP-MS is becoming the technology of choice for laboratories. The American Society for Testing and Materials (ASTM) issues standard D8110 that outlines the specifications and test method for elemental analysis of distillate products by ICP-MS. Analysis of combustible organic samples like naphtha, vacuum gas oil (VGO), or aviation turbine fuel (ATF) using ICP-MS could be challenging compared to conventional aqueous samples mainly because unexpected and intermittent extinguishing of plasma as well as carbon deposition in the interface region extracting ions into the mass spectrometer. The direct introduction of volatile organics increases the plasma load due to their high vapor pressure, causes destabilization of plasma and results in poor sensitivity and precision of measurements. Carbon-based interference on key analytes, such as chromium or vanadium, cause additional concerns but can typically be overcome using kinetic energy discrimination (KED) on single quadrupole instruments, or other typical gases used in collision/reaction cells1 . This poster discusses a complete workflow developed using the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1487">Thermo Scientific iCAP MSX ICP-MS</a> (Figure 1) for the sensitive determination of elemental impurities in typical distillate samples including light naphtha, heavy naphtha, and crude oil samples.<h4>Materials and methods</h4>An analytical method was developed with single quadrupole ICP-MS (iCAP MSX ICP-MS) for elemental analysis of a range of typical petroleum samples with varying physical and chemical properties.<h5>Data Analysis&nbsp;</h5>The data acquisition and processing were done using <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1489">Thermo Scientific Qtegra Intelligent Scientific Data Solution (ISDS) Software</a>.<h4>Conclusions&nbsp;</h4>The results obtained from the experiments described in this application note demonstrate the following:&nbsp;<ul><li>The proposed method and instrument set-up for elemental analysis of different petroleum products using the iCAP MSX ICP-MS represents a viable solution for laboratories performing oil and refinery product testing.&nbsp;</li><li>The combination of the sample introduction system together with a uniquely robust plasma generation system and a powerful CRC allows for sensitive analysis and comprehensive interference removal for all elements commonly analyzed in the industry.&nbsp;</li><li>The use of KED with helium provided effective for removal of polyatomic interferences commonly observed in such challenging matrices, as was demonstrated by the detection limits and blank equivalent concentrations (BECs) achieved.&nbsp;</li><li>The method therefore allows the accurate and precise determination of a total of 28 elements in different kinds of distillate products, as was demonstrated by the results obtained in the spike recovery test.&nbsp;</li><li>If needed, other reactive gases can be used in a multi-mode analysis performed during a single aspiration of a sample, including alternative cell gases such as hydrogen. Thanks to the fast gas switching in the QCell CRC, the added time for switching cell gases is often negligible for the overall analysis time per sample.&nbsp;</li><li>The novel design of the sample introduction system of the iCAP MSX ICP-MS allows to easily switch between oxygen addition and the use of argon gas dilution without the need to change gas connections.</li></ul>

LECO: Determination of Nitrogen in Fertilizer</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/CN_FP_928_NITROGEN_FERTILIZERS_203_821_615_4d4b013a08.pdf">Full PDF for download</a></li></ul>Nitrogen is one of the most important elements for plant development and is the macronutrient that is most often found to be deficient in arable soils used for crop production. Nitrogen plays a key role in the formation of enzymes and proteins, which promotes lush, vigorous growth and development in plants that often leads to an increase in the yield from the plant. Fertilizers are utilized to re-introduce nitrogen back into arable soils. Fertilizers can be grouped by their makeup and/or origins into categories including inorganic and/or synthetic (including nitrates, ammonium, and urea) and organic (including compost materials and manures). The accurate and precise determination of nitrogen in all fertilizer types is not only important in the process of blending and preparing the fertilizer material for use, but also will have significant impact on the commercial value and guarantee of the fertilizer.&nbsp;The CN928/FP928 is a macro combustion carbon and nitrogen/protein determinator that utilizes a pure oxygen environment in a high-temperature horizontal ceramic combustion furnace designed to handle macro sample mass. A thermoelectric cooler removes moisture from the combustion gases before they are collected in a ballast. The 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).<h4>Instrument Model and Configuration&nbsp;</h4>Thermal conductivity detectors work by detecting changes in the thermal conductivity of the analyte gas compared to the constant thermal conductivity of the reference/carrier gas. The greater the difference between the thermal conductivity of the carrier gas and the analyte gas, the greater the sensitivity of the detector. The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=24&amp;search=CN928">CN928</a>/<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=24&amp;search=FP928">FP928</a> 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. 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 single standard, forced through origin calibration using ~ 0.1 g of NIST 913b Uric Acid (33.23% N). Alternatively, LECO 503-530 LCRM Urea may be used for calibration.<h3>2. Shimadzu: Evaluation of Microscopic Foreign Matter in Recycled Plastics Using Dynamic Image Analysis, Infrared Microscopy, and SEM-EDS</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_00861_en_7485baba21.pdf">Full PDF for download</a></li></ul><h4>User Benefits</h4><ul><li>&nbsp;It is easy to evaluate the size and quantity of microscopic foreign particles, which are key quality criteria of recycled plastics.</li><li>With the microcell method of DIA, microscopic foreign matter can be detected and counted quickly using a small sample quantity.</li><li>Infrared microscope and SEM-EDS systems provide information about the morphology and composition of microscopic foreign matter that is useful for improving recycling processes.</li></ul>One of the quality criteria for recycled plastic flakes and pellets is the content of foreign matter. Quantitatively evaluating the size and quantity of foreign particles contained in flakes and pellets is important for examining foreign matter removal processes intended to improve pellet quality and optimize manufacturing processesfor products made with recycled materials.&nbsp;In this article, pellets of virgin and recycled polyethylene terephthalate (hereafter PET) were dissolved in hexafluoro-2-propanol (hereafter HFIP), a solvent for dissolving PET, to prepare suspensions of insoluble microscopic foreign particles. These suspensions were measured with a dynamic particle image analysis (DIA) system (<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=iSpect+DIA-10">iSpect DIA-10</a>) to evaluate the size and number of insoluble microscopic foreign particles (patent pending). In addition, part of the suspensions were diluted tenfold and filtered through a membrane filter to collect the insoluble microscopic foreign particles on the filter. The morphology and composition of the collected microscopic foreign particles were evaluated using a digital microscope, an infrared microscope system (<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=IRTracer-100">IRTracer-100</a> and <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=AIM-9000">AIM-9000</a>), and an SEM-EDS system. These evaluations enabled comparison of the sizes, quantities, and types of foreign particles contained in virgin and recycled materials.<h4>Conclusion&nbsp;</h4>By using an iSpect DIA-10 system to measure suspensions prepared by dissolving two types of PET pellets (virgin and recycled) in HFIP, we obtained particle images of insoluble foreign matter and evaluated size and concentration of particles. That enabled quantitative comparison of particle size and count in microscopic foreign matter contained in virgin and recycled materials.&nbsp;In addition, after diluting the pellet suspensions, the insoluble microscopic foreign matter in the diluted suspensions was collected on filters. The morphology and composition of the microscopic foreign matter were evaluated using an infrared microscope and SEM-EDS system. The results indicated that the suspensions contained organic substances, such as cellulose and amide-based compounds, and inorganic substances and metals that contain elements such as C, O, Ca, and Al (suggestive of carbonates and metallic aluminum).&nbsp;Thus, the iSpect DIA-10 enables simple quantitative evaluation of the size and number of microscopic foreign particles in PET pellets using only small sample quantities. Furthermore, composition evaluation by infrared microscope and SEM-EDS systems provides useful information for investigating the origin of foreign matter, examining measures to reduce foreign matter, and evaluating impacts on final products. If similarities in size and shape are observed, particle images obtained with iSpect DIA-10 can also potentially be used to estimate particle composition.<h3>3.

To prevent against such threats, manufacturers require high throughput technologies to better identify foreign particulate matter in real time.<h4>Results and Discussion</h4><h5>Shining a Light on Extrinsic Particles with SIMI</h5>Side illumination membrane imaging (SIMI) is a proprietary illumination, imaging, and analysis technique exclusively available to <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2190">Aura instruments</a>. Utilizing the principles of darkfield microscopy,6 SIMI is conducted on an Aura membrane plate using an oblique illumination source which emits light at an angle parallel to the surface of the plate.&nbsp;Compared to backgrounded membrane imaging (BMI), which utilizes brightfield microscopy (epi-illumination) where particles scatter the incident light isotropically (i.e., at all angles), side illumination membrane maging (SIMI) is a technique that is specifically designed to detect light scattering from high refractive index particles, as well as those that protrude out of the plane from the membrane surface. A particle’s average SIMI intensity is measured in a relative scale where the inherent SIMI scattering of the membrane is defined as SIMI = 0. Positive SIMI values indicate particles protruding out of the membrane, as is the case with microplastics, fibers, and other common extrinsic particles, whose average SIMI intensities vary from 0–255. On some occasions, like with metallic particles and absorbing oils, particles will have reduced light refraction relative to the membrane and thus display negative SIMI values, varying from 0 to -122.&nbsp;The majority of foreign, extrinsic particles exhibit a high refractive index and are mechanically rigid in structure, causing them to protrude from the membrane surface and scatter side illumination to a high degree, ideal for SIMI analysis. In contrast, biologic particles exhibit the opposite properties—low refractive index and malleable structures, causing them to lie flat with minimal side scatter profiles, which is best analyzed with BMI or fluorescence membrane microscopy (FMM). Utilizing all three microscopy approaches is most ideal to facilitate the determination of all extrinsic (non-biologic) and inherent (biologic) particles in biologic formulations.<h4>Conclusion&nbsp;</h4>SIMI is a unique approach to providing additional characterization of subvisible particles and is available in all Aura models to help rapidly identify foreign material in biological samples with a high degree of specificity. A key tertiary imaging mode in addition to BMI and FMM, SIMI provides selective, orthogonal morphological information to identify tall and rigid materials, a defining feature of most extrinsic particles (Figure 11). While particle sizing and counting is done via BMI, SIMI provides illumination, imaging, and analysis that can be useful across a variety of biological products to reveal foreign subvisible particles from the earliest to the latest of stages in the bioprocess.
