Type of Gas Chromatography Detectors

GC detectors can find the identity and concentration of analytes. Selective, non-selective and specific are the nature of GC detectors. Non-selective detectors react to all components present in a carrier gas; selective detectors have a response to a variety of compounds with the same chemical characteristics and specific detectors are the response to a specific compound. Flame ionization detector (FID) and thermal conductivity detector (TCD) are the most widely used detectors, both sensitive to a wide range of components, FID is highly sensitive and robust than TCD. FID does not react to inorganic gases and TCD is a response. to inorganic gases such as N2, CO, NH3, CO2, CS2, etc.

There are a large number of detectors used for gas chromatography, check it out.

• Flame ionization detector: (FID)
• Thermal conductivity detector: (TCD)
• Nitrogen and phosphorus detector: (NPD)
• Photoionization detector: (PID)
• Electron Capture Detector: (ECD)
• Photometric Flame Detector: (FPD)
• Electrolytic Conductivity Detector: (ECD)
• Mass spectrometer: (MS)
