To maintain accuracy, analysts must manage several chemical interferences:
: Moisture and water vapor must be removed using drying tubes to prevent "quenching," which weakens the fluorescence signal. Application and Precision 245.7z.001
The method relies on . Unlike traditional absorption methods, CVAFS measures the light emitted by excited mercury atoms. To maintain accuracy, analysts must manage several chemical
: 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 To maintain accuracy
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.
