ABSTRACT:
A thermal conductivity detector comprises a housing having an internal cavity, a fluid inlet, a fluid outlet, a first bore and a second bore. The thermal conductivity detector further comprises a thermistor having a first electrical lead and a second electrical lead, a first contact pin in electrical communication with said first electrical lead and a second contact pin in electrical communication with said second electrical lead. The first contact pin is oriented within the first bore, the second contact pin is oriented within the second bore and the thermistor is suspended within the gas analysis chamber.
