PID Analyzers - Model FP56 -Flame Photometric Detector (FPD)

The flame photometric detector (FPD) is used for the selective measurement of any S or P species that can be burned in a flame to product chemiluminescence. This corresponds to either small molecules like H2S or PH3 or large pesticides containing S or P. The detector is described below: The Model 56 has an FPD (burner), a photomultiplier tube (PMT), a HV power supply for the PMT, an interference filter for S (394 nm or P 525 nm), an electrometer and gauges and flow control for the support gases for the FPD (H2 and air). The electrometer output is 0-10 VDC. The customer needs a separate ADC channel to feed the signal into the GC’s data system. Alternately, PID Analyzers sells a data system (Model --) that will feed the signal into a separate PC. The FPD is very sensitive and very selective detector for S or P compounds. It has the wide dynamic range (>10⁶).
