ABSTRACT:
A thermal conductivity detector (TCD) utilizes a modular thermistor assembly that mounts to the TCD body. The thermistor assembly is easily replaceable in the TCD. Within the TCD, a thermistor bead is always held in the same relative location in a gas flow path, which is designed to produce laminar, low velocity gas flow across the thermistor bead. Two TCDs, each having a heater, are mounted in an insulated enclosure. The heaters are activated to bring the TCDs to operating temperature, and are then deactivated during analysis.
