: The use of high-purity argon (99.998%) is mandatory; using nitrogen or air significantly reduces sensitivity.

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. : The use of high-purity argon (99

) 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 meaning laboratories can use different equipment

: Gold, silver, and iodide can interfere with the reduction process.
