EPA Method 7000

EPA Method 7000 is a standardized laboratory procedure used to detect and measure mercury levels in water samples. It involves converting mercury in the sample into a vapor form through a chemical process, then collecting and analyzing this vapor using a device called a cold vapor atomic absorption spectrophotometer. This method is sensitive, accurate, and widely used for environmental testing to ensure water quality and safety by reliably determining trace amounts of mercury. It’s essential for regulatory compliance and pollution monitoring.
