Zusammenfassung:	A column assembly for gas chromatography, which is coolable by a fluid, includes a capillary column, a heating element for heating at least a portion of the capillary column, and a tube having a lumen and in contact with at least one of the capillary column and the heating element. When energized, the heating element raises the temperature of the capillary column. To lower the temperature of the capillary column, a fluid flows through the tube, and heat is transferred from the capillary column to the fluid in the tube.
