Abstract: This invention provides a reduced power consumption gas chromatograph system (10) which includes a capillary gas chromatograph column member (12) which contains a chemical sample to be analyzed. The gas chromatograph system further includes a heating mechanism (16) which extends throughout the length of the capillary gas chromatograph column member (12) and surrounds both the member (12) and a temperature sensing mechanism (14) which is mounted adjacent to the column member (12). The temperature sensing mechanism (14), the heating mechanism (16) and the column member (12) form a chromatograph column assembly (20) which includes a coiled section (28) where the components are tightly packed with respect to each other and allows for a reduced power consumption for temperature programming miniature gas chromatography column assemblies.

Abstract: A gas chromatography system includes a gas chromatography oven having a door adapted for integration with gas chromatography modules which are located outside of the oven cavity. For these purposes, the oven door has module receiving openings in which the modules are secured. The gas chromatography module includes a module housing containing a main coil of the capillary column, a pair of transfer lines sleeved on the free ends of the capillary column, a heater wire wound on the transfer lines, and, optionally, a pair of chromatography connectors which extend into the oven cavity and through which the free ends of the capillary column, as well as transfer lines, projecting into the oven cavity. A wall of the GC oven has an injector port and a detector port for injection of a sample into the oven cavity and for detecting the sample constituents. Column lengths extend within the oven cavity between the module and injector and detector, respectively.
