Working of Flame Ionization Detectors
Introduction Several detector designs exist for process gas chromatographs. The two most common are the flame ionization detector (FID) and the thermal conductivity detector (TCD). Other types of detectors include the photometric flame detector (FPD), the photo ionization detector (PID), the phosphor nitrogen detector (NPD) and the electron capture detector (ECD). All chromatography detectors exploit …
