Solvent preheating system for liquid chromatography

A heater assembly used in chromatography includes a thermally conductive base having a chamber extending fully through the base with an opening at a first side of the base and at a second side of thebase, and a cavity with an opening at the second side of the base. A heater is disposed within the cavity in thermal communication with the base. A thermistor assembly, having a thermistor within a thermally conductive body is disposed within the chamber. The body has a head region with a planar surface. The planar surface of the head region is exposed at the opening of the chamber at the first side of the base for making thermally conductive contact therewith. The thermistor assembly is thermally isolated from the base. 本发明提供了种用于色谱法的加热器组件，所述加热器组件包括导热基座，所述导热基座具有完全延伸穿过所述基座且在所述基座的第侧和所述基座的第二侧具有开口的腔室，以及在所述基座的所述第二侧具有开口的腔体。加热器设置在所述腔体内并与所述基座热导通。热敏电阻器组件设置在所述腔室内，所述热敏电阻器组件具有位于导热主体内的热敏电阻器。所述主体具有带有平坦表面的头部区域。所述头部区域的所述平坦表面暴露在所述腔室的位于所述基座的所述第侧的所述开口处用于与其进行导热接触。所述热敏电阻器组件与所述基座热隔离。
