ABSTRACT:
In a gas chromatograph assembly, a heat conducting block of relatively large mass has a plurality of cavities formed therein. One cavity houses the chromatographic column; another cavity, extending into close proximity to the first, houses a temperature sensing element; and a third cavity houses a heater. This assembly is secured to a heat transmitting base to which is also secured an explosion-proof housing which houses a detector block. The entire assembly is covered with insulation and the heater block maintains the chromatographic column and the detector block at substantially the same temperature.
