Detectors in Gas Chromatography

Compounds elute out from the column is detected by this system. Simply detector tells the user that a compound has been eluted out. Detector generates a response which indicates the presence of a compound eluting from a GC column. The respond varies with the compound.

Thus on the other hand detector not only detects the compound but also identifies the compound. This emphasizes that needfulness of a detector to GC is of utmost importance. There are two types of detectors. Those are as following,

• Flame ionization detector (FID)
• Thermal conductivity detector (TCD)
