Abstract

The invention discloses a carrier coating device of a capillary chromatography base pipe. The carrier coating device comprises an air inlet, an air inlet valve, a flow speed control valve and a copper pressure-resisting pipe which are in sealed connection in sequence through pipelines, wherein the pipeline between the flow speed control valve and the copper pressure-resisting pipe is further connected with an exhausting valve and a pressure gauge; the copper pressure-resisting pipe is provided with a cavity and a sealing cover; and the sealing cover is provided with a leading-in pipe for inserting the capillary chromatography base pipe. The invention further provides a method for coating the capillary chromatography base pipe with a carrier, so that ion liquid coating is well performed, and the coating effect of the ion liquid with middle and strong polarities is enhanced, and furthermore, the separation capability of fixed phases for some complicated samples is improved.

Description

technical field

[0001] The invention relates to the technical field of analysis, in particular to a capillary chromatography substrate coating device and a method for coating barium sulfate with the device. Background technique

[0002] Gas chromatography has become a very popular analysis method during the development of more than half a century. More than 1,000 stationary phases have been used in research and practical applications, and hundreds of stationary phases have become commercial products. Therefore, understanding the structure of gas chromatography stationary phases , performance and application, it is very necessary for gas chromatography experiment and research. The core of chromatographic separation is the chromatographic column, and the soul of the chromatographic column is the stationary phase. To establish a gas chromatography method, the most important thing is to choose a suitable stationary phase. Therefore, since the advent of gas-liquid chromatography...
