WebThermal Conductivity Detector. The TCD is a universal, nondestructive, concentration-sensitive detector that responds to the difference in thermal conductivity of the carrier gas and the carrier gas containing sample. It is generally used to detect permanent gases, light hydrocarbons, and compounds that respond poorly to the FID. WebIntroduction. The flame ionization detector (FID) is the most sensitive gas chromatographic detector for hydrocarbons such as butane or hexane. With a linear range for 6 or 7 orders of magnitude (10 6 to 10 7) and limits of …
