EPA Method 200.8 ICP-MS Trace Metal Testing
EPA Method 200.8 is a recognized standard for the determination of trace metals in drinking water using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This method ensures precise and accurate measurement, which is critical for ensuring compliance with regulatory standards set by the U.S. Environmental Protection Agency (EPA) and other governing bodies.
The primary focus of EPA Method 200.8 ICP-MS testing is to measure trace levels of metals in drinking water, including copper, lead, arsenic, cadmium, mercury, and chromium. These metals can be present due to natural sources or as a result of human activity such as industrial processes, agricultural runoff, and urban pollution.
The method involves several critical steps, starting with the collection and filtration of water samples. After filtering, these samples are analyzed using ICP-MS instrumentation, which provides high sensitivity and selectivity for trace metal elements. This allows laboratories to detect even minuscule amounts of metals that could pose health risks if present in concentrations exceeding safe limits.
The results from EPA Method 200.8 testing provide data critical for ensuring the safety and quality of drinking water supplies, which is paramount given the potential health impacts of trace metal contamination. Compliance with this method helps organizations meet regulatory requirements and maintain public confidence in the purity of their water sources.
| Parameter | Unit | Target Range |
|---|---|---|
| Copper | μg/L | |
| Led | μg/L | |
| Arsenic | μg/L | |
| Cadmium | μg/L | |
| Mercury | μg/L | |
| Chromium | μg/L |
The precision and accuracy of EPA Method 200.8 are achieved through rigorous quality control measures, including the use of certified reference materials (CRMs) and strict adherence to method-specific guidelines. This ensures that all laboratory results are reliable and repeatable.
Organizations across various sectors rely on EPA Method 200.8 ICP-MS testing to maintain compliance with regulatory standards and ensure public health protection. By detecting trace metals at levels far below the human perception, this method plays a crucial role in safeguarding water quality.
