Abstract
A gas chromatography (GC) column system includes an insulation tubing, a metallic GC column disposed within the insulation tubing and having an outer diameter that is less than or equal to an inner diameter of the insulation tubing, a first electrode in contact with the metallic GC column, and a second electrode in contact with the metallic GC column on an opposite side of the insulation tubing from the first electrode. The metallic GC column may be heated by applying a voltage across the first and second electrodes. The voltage may be controlled in response to a measured temperature of the metallic GC column.
