: 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. 245.7z.001

: Gold, silver, and iodide can interfere with the reduction process.
: High-purity argon gas carries the vapor into the CVAFS analyzer , where it is exposed to UV light (253.7 nm), causing fluorescence that is then measured. Critical Interferences
