ABSTRACT:
The invention relates to a temperature-controlled injector for a chemical analysis unit, in particular a gas chromatograph, comprising an injector tube, which can be received by a receiving tube, having a cooling system, which surrounds the receiving tube, through which coolant can flow, which has coolant connections and which is designed as a metallic tube coil, and a resistance heating system for the injector tube, in which injector the receiving tube consists of a material of good thermal conductivity, is electrically insulating towards the outside, and the tube coil rests on the receiving tube, has an electrical resistance which is sufficient to rapidly heat the injector tube and can be acted on by current via electrical connection pieces.
