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. Application and Precision To maintain accuracy

: Moisture and water vapor must be removed using drying tubes to prevent "quenching," which weakens the fluorescence signal. Application and Precision
