Preferred Label : thermal conductivity detector;
Detailed label : thermal conductivity detector in gas chromatography;
IUPAC definition : In general, two cells arranged in a bridge configuration detect the change in thermal
conductivity of the gas at the output of the column. This detector is sensitive to
any substance with thermal conductivity different from that of the carrier gas. The
lowest detectable limit is between 0.5 and 100 ppmv. The linear dynamic range is of
the order of 10E3. This type of detector is often used for measuring components at
relatively high concentrations.;
