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.

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.

Water forms 80% of the human body and is essential to all life. Due to increasing pollution and land disturbance, vast quantities of potentially harmful elements are mobilized into potable water sources, such as rivers, lakes and groundwater. As such, the concentrations of elements, which are known to elicit a toxicological response, are regulated throughout the world by international and national regulations, of which one of the most commonly used methods is the United States Environmental Protection Agency 200.8 (EPA 200.8). Since all drinking waters need to be tested prior to distribution to ensure fitness for consumption, this makes sample loads on water-testing laboratories high.

This study presents a high throughput method evaluating 27 analytes in drinking water following EPA 200.8 with a 3-5 fold reduction in sample analysis time through the use of PerkinElmer’s High Throughput System (HTS), a novel high-volume sample introduction module that is fully integrated with the NexION ICP-MS.

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.

Due to increasing urbanization, industrialization, mining, and farming practices within catchment areas, the need to monitor potable drinking water for hazardous components has increased in importance. Many countries have implemented stringent criteria which need to be met before water can be distributed for human use and consumption. This require that analytical instrumentation be capable of reaching low detection limits so that trace concentrations of elements can be accurately and precisely quantified.

In the textile industry, the use of titanium dioxide (TiO₂) nanoparticles (NPs) is increasing due to their ability to provide UV protection, increase the hydrophilic nature of fabrics, provide antibacterial characteristics, and reduce odors. This work demonstrates the ability of PerkinElmer's NexION^® Single Particle ICP-MS with Syngistix^™ Nano Application Software Module to both detect and measure TiO₂ nanoparticles released from textiles.

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.

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.

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.

Nanoparticles (NPs) have been of significant interest over the last two decades as they offer attractive benefits for drug delivery to overcome limitations in conventional chemotherapy. Nanoparticles can be engineered to carry both drugs and imaging probes to simultaneously detect and treat cancer. They may also be designed to specifically target diseased tissues and cells in the body. A number of nanoparticlebased cancer therapeutics have been approved for clinical use and/or are currently under development.

Testing for harmful metal(loid)s that may be included in raw materials, processes, paints and additives used in the manufacturing processes of children's toys has been mandated by the regulation EN 71-3.
