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
and
.
The linear dynamic range is of the order of
.
This type of detector is often used for measuring components at relatively high concentrations.
