Achieved column performance and lifespan are determined through chromatographic analysis. When installing a gas chromatography column, pay attention to the following points:

Select the appropriate chromatography column size and sealing pad material for the sample inlet and detector type.

Avoid reusing sealing washers.

Use appropriate column cutting tools, such as ceramic blades or diamond cutters, for column cutting.

Ensure the column head is clean and flat before installing the chromatography column between the injector and detector.

5 The requirements of an installation instrument gas chromatography column manufacturer: install the column at an appropriate distance from the injector and detector.

The 6 chromatography columns are placed on the column holder, ensuring no part of the capillary column comes into contact with the chamber wall.

Before the 7-column cylinder is heated, ensure all joints are leak-free and that the carrier gas contains no oxygen.

8 Verify the correct installation of the chromatographic column by injecting non-retained compounds or using a gas chromatography software program, and set the carrier gas linear flow rate.

Age the chromatography column according to the information provided with the column.
