色谱柱老化:
1.新填充的色谱柱
2.使用以后柱效下降的色谱柱
3.色谱柱种类:填充柱，毛细管柱，微径柱
4.材质:不锈钢，聚四氟乙烯，硬质玻璃
老化的方法通常是将色谱柱升至一恒定温度，通常为其温度上限。特殊情况下，可加热至使用温度之上约10～20℃左右，但是一定不能超过色谱柱的温度上限，那样十分容易损坏色谱柱。

Column aging:
1. Newly filled chromatographic column
2. Chromatographic columns with decreased column efficiency after use
3. Column types: packed column, capillary column, micro diameter column
4. Material: stainless steel, polytetrafluoroethylene, hard glass
The method of aging is usually to raise the chromatographic column to a constant temperature, usually at its upper temperature limit. In special circumstances, it can be heated to about 10-20 ℃ above the operating temperature, but it must not exceed the upper temperature limit of the chromatographic column, as this can easily damage the column.
