The thermal conductivity detector (TCD), also known as a Katharometer, is a bulk property detector and a chemical specific detector commonly used in gas chromatography. This detector senses changes in the thermal conductivity of the column effluent and compares it to a reference flow of carrier gas. Since most compounds have a thermal conductivity...

(from the article `chromatography`) Gas chromatographic detectors sense the solute vapours in the mobile phase as they emerge from the column. Thermal-conductivity detectors compare the ...

In sample analysis, uses a hot wire or a thermistor as the sensing device. The readout is based upon the heat transfer from the hot filament to a cooler surface as the gas conducts heat from the filament to the wall. The amount of electrical energy supplied to the filament remains constant so any change in temperature (of the filament) will be a fu...

A type of gas chromatographic detector which is sensitive to the change in the ability of the gases emerging from the column to conduct heat. A thermal conductivity (TC) detector is not as sensitive as a flame ionisation detector, but it is capable of detecting some molecules, such as water, which give no signal in FID
