Annotation of standard text ASTM E840-95(2021)e1 :

This practice is intended as a guide for the use of a flame photometric detector (FPD) as the detection component of a gas chromatographic system. The different principles of flame photometric detectors, and detector construction are presented in details. The detector sensitivity, minimum detectability, dynamic range, power law of sulphur response, linear range-phosphorus mode, unipower response range, noise and drift, and specificity are presented in details. The photomultiplier dark current is the magnitude of the FPD output signal measured with the FPD flame off. Flame background current is the difference in FPD output signal with the flame on and with the flame off in the absence of phosphorus or sulfur compounds in the flame.
