Abstract

A thermal conductivity detector includes not only a thermal conductivity detector cell disposed so as to be heated by heat transmitted from a first heater block and a column connector connected to the detector cell and to a column of a chromatograph but also a second heater block for heating the column connector. The heaters for individually heating these two heater blocks are controlled simultaneously and in synchronism by a single temperature controller according to the temperature of the first heater block for heating the detector cell.
