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.
