Rice represents a dietary staple for over half of the world's population. However, in recent years, concerns have been raised over the presence of high levels of arsenic (As), where this carcinogenic metalloid can be accumulated at levels far exceeding ambient concentrations. Since China is the world's largest producer of rice, the Chinese government released a national standard method in 2014 for food safety – GB 5009.11– to aid the evaluation of As species in rice and rice products. In this document, HPLC-ICP-MS is identified as the preferred analytical technique.

In this study, five arsenic species were characterized in a commercial rice sample and certified reference material using a gradient anion-exchange method in accordance with GB 5009.11. The analysis was performed using a PerkinElmer NexSAR^™ HPLC-ICP-MS speciation solution, consisting of a NexSAR inert HPLC coupled to a NexION^® ICP-MS.

Concern about air pollution has been growing rapidly, with most of the focus on gaseous pollutants. Airborne particulates, especially small ones, are rapidly gaining attention due to their impact on human health, as smaller particles can be carried over long distances by wind and penetrate deep into the lungs, where contaminants can have direct interaction with lung tissue and the associated blood vessels. Airborne particulates are classified as PM₁₀ for those with aerodynamic diameters less than 10 µm and PM_2.5 for those with aerodynamic diameters less than 2.5 µm.

PM_2.5 regulations have been implemented throughout the world, and in order to implement a regime to reduce the concentration of PM_2.5, it is important to determine the origins of these particulates, hence the need to collect and analyze them.

ICP-MS is often the analytical instrument of choice for such applications due to its low detection limits and wide linear dynamic range. This work describes the collection, sample preparation and inorganic elemental analysis of atmospheric PM₁₀ and PM_2.5 using PerkinElmer’s NexION^® ICP-MS.

Toxic cyanobacterial blooms were reported worldwide in various aquatic systems, including freshwater rivers, lakes, reservoirs, and eutrophied coastal marine habitats. Cyanobacterial blooms might be caused by a combination of multiple factors, including eutrophication, solar radiation, temperature, current patterns and other associated factors. Their proliferation in aquatic environments can cause death or toxin accumulation in aquatic animals and then, indirectly or directly, affect human health. Microcystis aeruginosa (M. aeruginosa) bloom is the most common harmful algal bloom (HAB) and is widely studied in various fields.

Copper sulfate is an algaecide frequently used for controlling algae growth. The mechanism of copper (Cu)-based algaecide for algal bloom control is not well understood. The amount of Cu required to kill an individual algae cell and the morphology of the cell after being killed is still unknown. Quantification measurement of these phenomena is even more difficult due to the lack of appropriate methodology.

This work demonstrates that single cell (SC)-ICP-MS provides an effective method for the determination of copper algaecide at the cellular level, leveraging the NexION^® ICP-MS with Syngistix^™ Single Cell Application software module.

This application note presents a high throughput method evaluating 27 analytes in drinking water following U.S. EPA 200.8 with a 3-5 fold reduction in sample analysis time through the use of the HTS high throughput sample introduction system fully integrated with the NexION^® ICP-MS and Syngistix^™ for ICP-MS software.

This work demonstrates a robust method using SP-ICP-MS technology to detect CeO2 NPs which were extracted from soil samples with tetrasodium pyrophosphate (TSPP). Over the past few decades, engineered nanoparticles (ENPs) have been increasingly used in many commercial products. As a result, more and more ENPs have been released into the environment, which raises concerns over their fate, toxicity and transport therein.

The most significant challenge in trace element analysis of drinking water is ensuring detection capability that complies with the regulatory framework at the same time as maximizing sample throughput. The NexION^® 1000 ICP-MS solves the challenges that high-throughout laboratories face using a robust, simple method and a single gas mixture. This application note explains how the NexION 1000 exceeds expectations on detection capability and details the benefits of using the single gas mixture for a wide range of elements, even those where the first ionization energy is relatively high (e.g. selenium).

Boron (B) is studied for its isotope ratio composition in a range of paleoproxy, geochemical, nuclear, medical, and archeological applications. ICP-MS is recognized as a powerful technique for boron isotope analysis. Quadrupole ICP-MS is versatile and not exclusively dedicated to isotope ratio measurements, therefore the appreciation of its isotope ratio capabilities can bring high-quality isotopic ratio analysis into the reach of laboratories with varied analysis needs.

This application note describes the analysis of boron isotope ratios using a NexION^® ICP-MS, demonstrating the instrument’s capabilities to measure at the best possible level of precision.

Consumption of seafood is the primary exposure route of methylmercury for humans, emphasizing the importance of accurately measuring methylmercury in fish. As with all analytical method setup, the determination of methylmercury content in fish has to meet the criteria of modern analytical methodology, including reproducibility, repeatability, and accuracy at low concentrations. These characteristics are facilitated by using an HPLC system with a metal-free flow path, which eliminates the possibility of mercury leaching into the mobile phase, thereby affecting the lowest concentrations which can be measured.

This work demonstrates the accurate and reliable determination of methyl- and inorganic mercury in fish using PerkinElmer’s NexSAR™ HPLC-ICP-MS speciation solution, leveraging the inert, metal-free flow path of the NexSAR HPLC system in combination with the robust and versatile NexION^® ICP-MS.

Eye drops are commonly used medications which are available both over-the-counter and as prescriptions in various forms. Because eye drops are classified as a parenteral medication and have relatively large daily doses, the inorganic components in eye drops must be present at low concentrations. As a result, ICP-MS is the most appropriate technique for the determination of trace elements in eye drops.

The International Conference on Harmonization Guideline for Elemental Impurities Q3D (ICH Q3D) has established maximum permitted daily exposure limits for elemental impurities in pharmaceutical products. This work discusses the sample preparation and analysis of Class 1, 2, and 3 elements in a variety of eye drops with the NexION ICP-MS, following the criteria defined in ICH Q3D. The developed methodology (both sample preparation and analytical) demonstrates both accuracy and stability.

Owing to the toxicity of heavy metals, it is increasingly important to test cannabis flowers and other cannabis derivatives so that patient and consumer safety is maintained as the use of cannabis becomes more common. This need has translated into an increasing demand for testing cannabis flowers and other cannabis derivatives for toxins such as the heavy metals cadmium (Cd), lead (Pb), arsenic (As), and mercury (Hg). In this application note, we present data to illustrate the successful validation of the Titan MPS^™ Microwave Sample Preparation System and the NexION^® ICP-MS for the determination of heavy metals in cannabis flower according to the validation protocols set in USP General Chapter <233>, which are commonly used for evaluation of the levels of elemental impurities in samples.

Gold nanoparticles (AuNPs) are widely used in industrial and medical applications. They are known to form naturally during the weathering of Au-bearing mineral deposits, as well as the transformation of gold nuggets and particles. In freshwater systems, they bioaccumulate in aquatic organisms, as shown on test fish species such as zebrafish and guppy.

Several techniques are available to determine gold concentrations in samples – however, few methods have been developed to characterize the size fractions of nanoparticulate gold in complex organic materials. This work is a feasibility study to measure AuNPs in complex organic matrices using Single Particle ICP-MS, as may be applied to environmental monitoring or exploration, demonstrating the ability of PerkinElmer’s NexION^® ICP-MS Single Particle Analyzer to reliably detect and characterize nanoparticles in soil and aquatic samples.

Single Particle (SP) ICP-MS is an analytical technique that has demonstrated tremendous potential for the measurement and characterization of metal-containing nanoparticles (NPs) in a wide range of sample types, including environmental. One of the most challenging matrices is seawater due to its high salt content, which causes severe difficulties when analyzed for NPs due to matrix suppression and cone clogging.

This work demonstrates the ability of the NexION^® ICP-MS, coupled to the dedicated Syngistix^™ Nano Application software module, to measure silver (Ag) nanoparticles in seawater and track their transformations over time.

The analysis of elemental content is critical to ensuring the quality and safety of drinking water. In this regard, the international standard method ISO 17294 outlines the analysis of elements in water samples using ICP-MS, providing the general guidelines for using the ICP-MS technique as well as the determination of selected elements. Directive (EU) 2020/2184 aims to protect human health from the adverse effects of any contamination of water intended for human consumption by ensuring that it is wholesome and clean.

ICP-MS technology is ideal as it offers multi-element detection capability, low detection limits, high-speed of analysis, wide dynamic range, etc. However, it is affected by plasma as well as matrix-based polyatomic interferences and doubly charged species, which need to be accounted for by applying mathematical corrections and/or collision/reaction mechanisms.

This work demonstrates the ability of the NexION^® 1000 ICP-MS with Universal Cell technology, which can be operated in both Collision and Reaction modes to tackle polyatomic interferences, to meet and/or exceed the specifications contained within the ISO and EU directives for the analysis of drinking water.

The elemental analysis of soils is of vital importance not only for agriculture, but also from an environmental perspective. Toxic metals enter soil primarily through pollution and can be taken up directly by humans in various manners, potentially causing acute or chronically toxic responses. Therefore, the identification of pollutants and determination of the level of toxic elements present in the soil are important aspects to be considered.

This work demonstrates the ability of the NexION^® ICP-MS to easily analyze 21 elements in soil over an extended period of time with outstanding accuracy and stability, delivering a complete solution to addressing the challenges in soil analysis.

Due to rising concerns over the carcinogenic properties of hexavalent chromium (Cr⁶⁺) in drinking water, many national and regional water standards are looking to lower the maximum allowable levels of total chromium and hexavalent chromium in potable waters. And in order to assess trace concentrations of Cr⁶⁺ in drinking water, it is necessary to have an instrument capable of measuring parts per trillion (ppt) concentrations of Cr and possessing a wide linear dynamic range – HPLC-ICP-MS is often the instrumentation of choice in such applications.

This work demonstrates an ion exchange method for the characterization of Cr⁶⁺ in potable drinking water using our NexSAR HPLC-ICP-MS Speciation Solution.

With the onset of the COVID-19 pandemic, the use of face masks by the general public has become a critical personal protective measure to minimize person-to-person transmission. While health care workers use medical or surgical masks, the general population uses non-medical, otherwise known as hygienic, face masks to greatly reduce the transmission of SARS-CoV-2 by capturing droplets and aerosols from those infected with the virus.

In response to the increased demand for both the number and variety of non-medical face masks, many companies are now producing them to meet the public’s need, and with this great variety, the quality and the safety of the face masks must be assessed. This work describes the considerations surrounding metal analysis in hygienic face masks used to prevent the spread of COVID-19.
