Abstract
The present invention enables the dissipation of thermal energy from a gas chromatography chamber containing a gas chromatography sample by providing the housing in two parts so that ambient air can be bled in during a creation of thermal energy with a heater and additional ambient air can be circulated in a cooling cycle. Additionally, a heat exchanger for receiving liquid nitrogen can also be included to increase the speed in which thermal energy can be dissipated.
