Agilent Technologies: Navigating Global Microplastics Regulations in Drinking Water with Vibrational Spectroscopy</strong></h3><p><strong>Ensuring accurate and reliable microplastics characterization with the 8700 LDIR</strong></p><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/wp_microplastics_drinking_water_regulations_8700_ldir_5994_8166en_agilent_ea9c07e61c.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Access to clean and safe drinking water is a fundamental human right and a critical public health priority. With growing concerns about environmental pollution, emerging contaminants such as microplastics have become a major focus for regulatory bodies worldwide. Microplastic particles, originating from sources such as industrial waste, packaging, and everyday consumer products, have been detected in diverse water sources, raising concerns about both their potential health risks and environmental impact.</p><p>The accurate and reliable characterization of microplastics presents significant analytical challenges due to the diversity in size, shape, and composition of these materials. Particles range from less than 20 µm to visible fragments and can exist in various forms including spheres, fibers, and irregular shapes. Microplastics are typically composed of various types of polymer, each with distinct physical and chemical properties and unique degradation histories. Because of this complexity, analyzing microplastics requires advanced analytical techniques.&nbsp;</p><p>To address these challenges, regulatory bodies and standardization organizations have actively been developing guidelines and testing methods to monitor and control microplastics contamination in drinking water. The analytical techniques used to characterize microplastics are critical in achieving accurate and reliable outcomes when studying the impact of this emerging class of contaminant. The primary techniques used to analyze microplastics fall into two categories:&nbsp;</p><ul><li><strong>Thermo-analytical methods</strong> such as thermal extraction desorption gas chromatography-mass spectrometry (TED-GC/MS) and pyrolysis-GC/MS, which provide information about polymer type and mass1&nbsp;</li><li><strong>Vibrational spectroscopy methods</strong> including Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy, which provide information about polymer type, number of particles, and size</li></ul><p>There has been an ongoing effort for several years to standardize methods for microplastic analysis using vibrational spectroscopy. These standard methods provide structured approaches that help to ensure consistent, accurate, and reproducible microplastics analysis across different laboratories and regulatory environments.&nbsp;</p><p>Three such regulatory frameworks have been established by the following bodies:&nbsp;</p><ul><li><strong>Commission Delegated Decision (EU) 2024/1441</strong>: Supplementing Directive (EU) 2020/2184 of the European Parliament and of the Council by laying down a methodology to measure microplastics in water intended for human consumption.2</li><li><strong>California Water Boards</strong>: Policy handbook establishing a standard method of testing and reporting of microplastics in drinking water, August 9, 2022.3 The policy handbook was developed in response to State of California legislation (SB1422) requiring monitoring for microplastics. As noted in the introductory text, the method is designed to "[set] forth the requirements for conducting monitoring and reporting of microplastics in drinking water." Attachment C to that document (SWB-MP1-rev1) is a Standard Operating Procedure that describes the method as relevant to IR techniques.4&nbsp;</li><li><strong>ISO/DIS 16094-2: </strong>Water Quality — Analysis of Microplastic in Water, Part 2: Vibrational spectroscopy methods for waters with low content of suspended solids including drinking water (under development).5&nbsp;</li></ul><p>ASTM WK87463 (New Test Method for Spectroscopic Identification and Quantification of Microplastic Particles in Water Using Infrared (IR) Spectroscopy) is also under development. As this method has not yet been published, it is not covered by this white paper.6</p><h4><strong>Requirements of regulatory methods</strong></h4><h5><strong>Minimum and maximum particle size&nbsp;</strong></h5><p>It is necessary to check the accuracy of any particle-sizing data generated by the analytical method used for the analysis of microplastics. The three regulatory frameworks summarized in Table 1 specify a minimum detectable particle size of 10 to 20 µm using IR spectroscopy.&nbsp;</p><p>To demonstrate the performance of the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;search=8700+LDIR&amp;sources=GCMS_EN-ICPMS_EN"><strong>8700 LDIR</strong></a>, 10, 20, and 50 µm NIST-traceable polystyrene latex beads were measured on a low-e slide. As shown in Figure 5, particles were detected using the automated Particle Analysis workflow within the Clarity software. The method also correctly identified the type of particles, with a hit quality index (HQI) of &gt; 0.95, demonstrating the characterization capabilities of LDIR for particles as small as 10 µm. Additional details on particle sizing using gold- and aluminum-coated filters are available in other publications.8,9</p><p>As stated in Table 1, the maximum required measurement size across the three regulatory frameworks is 5 mm for particles and 15 mm for fibers per EU 2024/1441. While LDIR analyzes particles up to 500 µm, larger particles can be detected visually and measured using an Agilent <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?manufacturerItems=1&amp;sources=GCMS_EN-ICPMS_EN&amp;search=Cary+630+FTIR"><strong>Cary 630 FTIR</strong></a> spectrometer fitted with a diamond attenuated total reflectance (ATR) module (Figure 6). A fast and simple method for identifying plastic debris in this size range is reported elsewhere.10</p><h4><strong>Conclusion&nbsp;</strong></h4><p>Microplastics are widespread in the environment, exhibiting significant variation in size, shape, color, and composition, which complicates their analysis. To address these challenges, current regulatory frameworks and emerging analytical methods offer flexibility in sampling equipment, instrumentation, and data analysis techniques, provided they meet the required analytical standards. The aim of the standardized methods is to improve the accuracy and comparability of microplastic assessments. In addition to thermo-analytical methods and vibrational spectroscopy techniques such as μ-FTIR and μ-Raman, quantum cascade laser-based IR technology has proven to be a suitable technique for microplastic analysis. This white paper demonstrates how an Agilent 8700 LDIR chemical imaging system combined with Agilent Clarity software meets the requirements of the three global regulatory frameworks, enabling accurate microplastics characterization. The laser-based system offers a fully automated workflow for the direct filter-based analysis of microplastics, resulting in significant time savings and higher sample throughput compared to conventional vibrational spectroscopy techniques.</p><h3><strong>2.

However, their resistance to degradation and concerns over their persistence in the environment and toxicity to organisms mean they are increasingly regulated throughout the world. As one of the pollution routes of PFAS, the atmospheric dispersion of PFAS exhaust gas emitted from factories using PFAS is a concern. Therefore, monitoring studies have been conducted considering the risk of long-term exposure of PFAS to the respiratory system and the spread of PFAS pollution from atmosphericdispersion of PFAS.&nbsp;</p><p>Because of the tightening of PFAS regulations, analytical methods are being developed for a variety of matrices, including water, soil, and food. While most of these methods target non-volatile (ionic) PFAS and use a liquid chromatograph-mass spectrometer (LC-MS/MS), volatile or semivolatile neutral PFAS are not easily measured by these methods, so a gas chromatograph-mass spectrometer (GC-MS) is suitable forthose compounds.&nbsp;</p><p>In this Application News, the TD-30R thermal desorption system coupled to a GC-MS system (<a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?manufacturerItems=3&amp;search=GCMS-QP2020+NX"><strong>GCMS-QP2020 NX</strong></a>) measured the quantities of nine volatile and semivolatile neutral PFAS (Table 1) in ambient air.</p><h4><strong>Spike-and-Recovery Test with Ambient Air&nbsp;</strong></h4><p>Standard solutions were prepared containing 10 ng of four FTOHs and 1 ng of three FTACs and two FOSAs and these standard solutions were added to the Tenax TA/Carboxen 1000 sample tubes. 20 L of ambient air was also collected at 100 mL/min. Spike-and-recovery test and repeatability results are shown in Table 5 and SIM chromatograms are shown in Fig. 3. The recovery rates were between 77 and 106 % and all concentration %RSD (n = 3) were below 8, showing generally good performance.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>The TD-30R and GCMS-QP2020 NX were used to measure quantities of nine neutral PFAS in ambient air. The measurements of standards demonstrated favorable results for sensitivity, calibration curve linearity, and repeatability for all the targeted compounds. A spike-and-recovery test with ambient air also demonstrated favorable results for recovery and repeatability. Using the TD-30R during sample pretreatment allows the sampling tube to be analyzed directly without a solvent extraction, enabling high-throughput analysis.</p><h3><strong>3.

Over 62 million tonnes was generated globally in 2024.1 However, only a small fraction of this waste is properly recycled, contributing to environmental pollution and the loss of valuable materials. To address this issue and to improve the safety of electrical and electronic equipment (EEE), the EU first introduced the Restriction of Hazardous Substances (RoHS) directive in 2003.2 By restricting the use of specific hazardous materials such as lead, mercury, cadmium, hexavalent chromium, and certain flame retardants, RoHS helps ensure that products are safer for both consumers and the environment.3 As the design, type, and production of EEE evolve, ensuring compliance with RoHS regulations becomes increasingly challenging for manufacturers, importers, and distributors. Plastics, such as polyethylene (PE), polycarbonate, polystyrene, polyethylene terephthalate (PET), polyvinylchlorate (PVC), and acrylonitrile butadiene styrene (ABS), are often used in EEE because of their unique properties and cost-effectiveness.4 Manufacturers must rigorously test these materials using advanced analytical techniques to detect and quantify restricted substances, ensuring compliance with the stringent limits set by the directive. Among these techniques, Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) is one of the most effective tools for analyzing elements in plastics in accordance with RoHS regulations.5&nbsp;</p><p>This application note describes a RoHS-compliant testing method for the multi-elemental analysis of plastics using an Agilent 5800 Vertical Dual View (VDV) ICP-OES. The methodology includes detailed procedures for sample preparation of a PE Certified Reference Material (CRM) and two real-life plastic materials used in EEE, instrument parameters, and performance evaluation. Quantitative results for arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), mercury (Hg), tin (Sn), antimony (Sb), sulfur (S), and zinc (Zn) are presented. The data set demonstrates the suitability of the method for supporting manufacturers in achieving RoHS compliance with a high level of efficiency and accuracy.</p><h4><strong>Results and discussion</strong></h4><h5><strong>Sample analysis – spike recovery and precision&nbsp;</strong></h5><p>Spike recovery tests in a sample matrix are an effective way to evaluate the reliability of the sample preparation and/or analytical methods, especially when suitable CRMs are unavailable. In this study, in addition to the analysis of the CRM, two real-life samples (A and B) were analyzed using the 5800 VDV ICP-OES. The measured concentrations of the analytes and spike recovery results are shown in Table 6. The spike recoveries for all analytes were within 94 to 108%, except for Sn in sample A, which had a spike recovery of 88%. This lower recovery could be due to the high measured concentration of Sn in sample A.&nbsp;</p><p>However, the recovery of Sn in the CRM was 104%, assuring the method’s accuracy. The %RSD of the spike recovery measurements (n=3) was used to evaluate the method’s precision. As shown in Table 6, the spike recovery RSDs were ≤2.3% for all nine analytes in both samples A and B. This method validation data confirms the effectiveness of the microwave digestion sample preparation procedure for these materials. The results also demonstrate the excellent reproducibility and reliability of the 5800 VDV ICP-OES method for the analysis of complex plastic matrices.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>The Agilent 5800 VDV ICP-OES was used for the quantitative analysis of nine elements including RoHS-specified elements, Cd, Cr, Pb, and Hg, in plastics that are typically used in electrical and electronic equipment (EEE). The samples included a plastic-based CRM (ERM-EC 681, polyethylene) and two real-life plastic matrices used in consumer electronics and electric vehicles. A one-stage microwave digestion sample preparation procedure ensured the complete digestion of these tough thermoplastic materials, facilitating accurate analysis by ICP-OES.&nbsp;</p><p>The 5800 ICP-OES demonstrated outstanding sensitivity, accuracy, and stability, making it a reliable solution for EEE manufacturers required to comply with RoHS or equivalent testing standards. The Intelligent Rinse software feature of Agilent ICP Expert Pro streamlined operations by automatically adjusting rinse times based on user-defined thresholds, saving time and resources, and lowering the overall costs of analysis. This study highlights the 5800 ICP-OES instrument’s capability to deliver precise and consistent results, supporting the industry’s need for rigorous and reliable RoHS compliance testing.</p><h3><strong>2.

With over 9,000 employees and 270 laboratories, Element is providing their services worldwide to 55,000 customers working in diverse sectors including aerospace, energy, environmental, industrials, and life sciences.&nbsp;</p><p>The Element Edmonton laboratory is ISO 17025 accredited, specializing in inorganic analysis. With three <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products?category=228&amp;manufacturerItems=3"><strong>ICP-MS</strong></a> and five<a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products?category=251&amp;manufacturerItems=3"><strong> ICP-OES</strong></a> systems, it analyzes for inorganic metals in soils and waters. Typical clients come from different industries such as oil and gas, construction, agriculture, municipal drinking water, and many more.&nbsp;</p><p>Alexsandra Robert is a senior scientist who has been working with the company for 20 years, with over 15 years of experience with ICP analysis. ICP-MS analyses performed at the Edmonton facility are primarily testing for heavy metal contaminant levels in soil and water. “<i>As the primary production lab for Element in Alberta, we currently analyze over 40,000 soils and 15,000 waters annually for metals</i>,” stated Alexsandra.&nbsp;</p><p>Analysis of soils and waters for elemental contaminants or minerals is typically performed using either Inductively Coupled Plasma – Optical Emission Spectroscopy (ICP-OES) or Inductively Coupled Plasma – Optical Mass Spectroscopy (ICP-MS) to satisfy the different analytical and regulatory requirements of customers. “<i>The choice between ICP-OES and ICP-MS is largely driven by factors such as required detection limits, number of analytes, regulatory guidelines, and type of information requested by our clients,</i>” Alexsandra further illustrated.</p><p>Busy analytical testing laboratories experience tremendous workloads and need to ensure that reliable results are delivered to their valued customers in time. Alexsandra noted, “<i>Achieving reliable analytical results with minimum time and resources is very critical to the overall success of any analytical laboratory.</i>” A Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1487"><strong>iCAP™ MSX ICP-MS</strong></a><strong> </strong>driven by Thermo Scientific™ <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1489"><strong>Qtegra™ Intelligent Scientific Data Solution Software</strong></a> was added to the instrumental portfolio of the Element laboratory in Edmonton and has been in use for testing of environmental samples including ground waters, lake waters, surface waters, and different types of soil samples. Whereas the analysis of water samples is relatively straightforward, soil samples need to be acid digested either by microwave or hot plate digestion before introducing them into the ICP-MS for analysis. Samples are typically diluted off-line prior to analysis using ultrapure diluent to ensure that total dissolved solids in samples do not exceed the tolerance level of ICP-MS instruments. Alexsandra provided insight on the typical workflow of an environmental laboratory, “For laboratories analyzing hundreds of samples every day, off-line liquid dilution is a tedious, error-prone, and expensive analytical step as it requires time, manual intervention, and expensive reagents and apparatus.”</p>
