PID Analyzers - Model FI53 -Flame Ionization Detector (FID)

The flame ionization detector (FID) is used for the selective measurement of any organic species that can be ionized in a flame. This corresponds to most hydrocarbons and is described below: The Model 53 has an FID (burner with HV bias and collector), a power supply for the FID bias, an electrometer and gauges and flow control for the support gases for the FID. 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 53) that will feed the signal into a separate PC. The FID is a sensitive and very selective detector for hydrocarbons. It has the wide dynamic range (>10⁶).
