In the whole capillary gas chromatography, the installation of the column 2ml GC vials manufacturer is particularly important, and the quality of the column installation directly affects the detection results. Therefore, a good capillary GC column and a well-designed chromatographic system must also be properly installed in the system to achieve good results.
Before the capillary GC column is connected to the detector, first turn on the carrier gas. Look at the outlet of the column for carrier gas. If there is no carrier gas coming out of the column, there is a place in the system in front of the column to deflate or the column. If it is blocked, find out the cause and solve it. Then extend the end of the column as far as possible to 1-2 mm below the nozzle of the side detector. And the high velocity region of the dry gas stream at the outlet of the column, if the column does not extend directly below the nozzle of the detector 1-2 mm, but must extend to the upper part of the tail gas inlet so that the end of the column is in the high velocity region of the gas stream .
The development and trend of capillary gas chromatography columns 2ml GC vials manufacturer in the past two years. The gas chromatography column column process is a mature technology, so the research on the column preparation process is not active enough. In recent years, the newly studied stationary phase has concentrated on normal temperature ionic liquids and various cyclodextrin derivatives.
This is the end of the introduction of How to link the GC column to the detector. I hope it can help you.
