Environmental Resources – NexION 1000
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.
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.
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.
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.
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.
Single particle ICP-MS (SP-ICP-MS) has become an essential tool for the analysis of nanoparticles (NPs) in various environmental matrices.
