This method is performance-based, meaning laboratories can use different equipment, such as the PSA Millennium Merlin or Teledyne QuickTrace , provided they meet strict quality control standards. It typically operates within a calibration range of 5 ng/L to 100 ng/L.
) concentrations in various water sources, including drinking water, surface water, and industrial wastewater. It is favored for its high sensitivity, allowing for detection at parts-per-trillion levels. Technical Principles 245.7z.001

EPA Method 245.7 is a specialized analytical procedure used to determine mercury ( Application and Precision
: The use of high-purity argon (99.998%) is mandatory; using nitrogen or air significantly reduces sensitivity.
: Moisture and water vapor must be removed using drying tubes to prevent "quenching," which weakens the fluorescence signal. Application and Precision
