Gas chromatography column coiling device

Abstract

A gas chromatography tube winding device includes a chromatography tube and a winding assembly. The chromatography tube includes an inner end and an outer end, the inner end being located at the innermost side of the chromatography tube and the outer end being located at the outermost side of the chromatography tube. The winding assembly includes a receiving groove, an inlet section, and an outlet section, the receiving groove being connected to the inlet section and the outlet section respectively. The inner end corresponds to the inlet section, and the outer end corresponds to the outlet section. The receiving groove is used for winding the chromatography tube, providing precise spatial constraints, and its walls guide the chromatography tube to be tightly wound sequentially from the outside to the inside to form a spiral shape.

Claims
