The purpose of the newly purchased gas chromatographic column aging is to drive away the residual solvent of the stationary phase, low-boiling impurities, low-molecular-weight fixative, etc., so that the baseline of the recorder is straight, and the fixative has a solution on the surface of the support at the aging temperature. The distribution process is thus applied more evenly and firmly. The packed column is stable after a period of aging, so that it can be used Thermo Fisher HPLC vials china manufacturer.
The principles of aging of gas chromatography columns are as follows: 1. When setting the aging temperature, never exceed the maximum use temperature of the fixed solution. 2. According to the percentage of the fixed solution, the aging temperature is set reasonably. The column with low content of fixed solution has a relatively low aging temperature. 3. The aging time is related to the sensitivity and type of the detector used. The higher the sensitivity, the longer the aging time is required. 4. The length of aging time also depends on the characteristics of the fixed liquid, "gas chromatography pure" is less than "industrial pure".
Although the aging process of the chromatographic packed column takes a certain amount of time, it can be obtained with a long column life! Good stability and small tailing, so it is very necessary and worthwhile. If the column is left for a while after use, don't forget to “re-age” the column, otherwise you will not get good results Thermo Fisher HPLC vials china manufacturer.
This is the end of the introduction of Newly purchased GC columns require aging principles. I hope it can help you..jpg)
