Background

In recent years, gas chromatography capillary column technology has been widely used in laboratories, and with the development of capillary column technology, capillary columns gradually replace packed columns. The advantage of capillary columns is a significant increase in separation efficiency compared to packed columns, where the analysis time is less than for packed columns at a given degree of separation. The capillary column has a much higher phase ratio than the packed column, can analyze high boiling components at a lower column temperature, and has the advantages of low stationary liquid consumption, thin liquid level, low operating temperature, low stationary liquid loss, and small baseline drift during temperature programming, so that the stability and signal-to-noise ratio of the detector are improved. Capillary columns are therefore an increasingly important choice for gas chromatography laboratories. However, the cost of a capillary column is high, the cost of one capillary column is often several times or even dozens of times of the cost of one packed column, and how to reduce the cost and the cost is also a problem to be considered in a laboratory. For bonded cross-linked capillary columns, it is a good choice to wash the capillary column with a solvent, and a suitable solvent can be selected to wash the inner wall of the column, so that the capillary column is regenerated, and the service life is prolonged. One capillary column can be cleaned for 4-6 times according to different pollution conditions, the cleaned capillary column can be reused, and the laboratory analysis cost is reduced.

However, the problems of low cleaning efficiency and incomplete cleaning can occur when the capillary column is cleaned by using the liquid solvent, and in addition, the speed and the flow in the process of washing the capillary column by using the liquid solvent are not controllable, so that the cleaning effect is difficult to ensure. Therefore, the utility model provides a gaseous belt cleaning device of quartzy capillary column for solve above-mentioned problem.
