FPD
In the Flame Photometric Detector (FPD), the column effluent is mixed with
hydrogen and then burned in air. Light emitted from the flame passes through a
lens, a filter, and to a photomultiplier tube, which generates an electrical signal.
The Flame Photometric Detector is used for detecting sulfur, phosphorus, or tin
compounds, which produce chemiluminescent reactions with emissions at
wavelengths characteristic of the S2, Sn, and HPO species.
The following screens show the Active Method screen and the corresponding
