Abstract

The invention belongs to the field of analysis and testing, and relates to the development of a miniaturized low-temperature chromatographic column box. The feature of this device is that the refrigeration module is made of heat-conducting adhesive solidified at room temperature, and the capillary chromatographic column used for separation is also solidified in the middle of the refrigeration module. Using a 4cm x 4cm x 0.2cm semiconductor element for refrigeration does not require traditional liquid nitrogen or liquid carbon dioxide refrigerants. The entire column box has a volume of only 6cm×6cm×2.5cm, which is simple and convenient, and has low manufacturing cost.

Description

technical field

[0001] The invention belongs to the field of analysis and testing, and relates to the development of a miniaturized low-temperature chromatographic column box. The feature of this device is that the refrigeration module is made of heat-conducting adhesive cured at room temperature, and the capillary chromatographic column used for separation is solidified in the middle of the refrigeration module. Utilizes a 4 cm x 4 cm x 0.2 cm semiconductor element to refrigerate, without the need for traditional liquid nitrogen or liquid carbon dioxide refrigerants. The entire column box has a volume of only 6 cm x 6 cm x 2.5 cm, which is simple and convenient, and has low manufacturing cost. Background technique

[0002] The background and development status of this technical field are roughly as follows:

[0003] The development of low temperature chromatographic separation technology has become one of the ways to solve the separation of volatile or...
