Zusammenfassung:	A chromatograph column and detector in separately controlled ovens spaced by an air gap are connected by a conduit that has a thermally conductive sheath, at least in the region of the air gap, which sheath is thermally attached to the detector oven to substantially prevent a cold spot (negative temperature gradient) when the temperature of the column approaches the temperature of the detector in programmed operation.
