摘要： A heating apparatus for a gas chromatography column is described. The GC column heating apparatus includes a conical heater assembly comprising a heating element between an inner layer and an outer layer. The apparatus can also include optionally an outer cowl and/or an inner cowl surrounding the conical heater assembly. The conical heater assembly rapidly increases the temperature of the column by conductive heating. The selection of shape (in particular, the cone angle of a conical heater) and materials allows the GC column to adapt to expansion that occurs upon heating. A gas chromatography (GC) column heating and cooling apparatus is also described, in which the heater and outer cowl define a flowpath through which a cooling fluid can pass and cool the GC column.

摘要： In gas chromatography (GC), a sample is introduced into a flow of carrier gas and the mixture is driven through a heated GC column to acquire chromatographic data from the sample. During this time, the column is heated from an initial temperature to a final temperature. Subsequently, the column is cooled according to a cooling program. The cooling program may include a first cooling ramp, a subsequent isothermal hold, and a subsequent second cooling ramp. Alternatively, while the column is cooled down the flow of carrier gas through the column may be slowed down or ceased for a period of time, after which the flow of carrier gas through the column may be resumed at the original flow rate in preparation for processing another sample. Controlling column temperature and/or flow in this manner may be effective for reducing column bleed carryover and/or the effects thereof.
