The protective column provides convenient, economical, and effective protection for the chromatographic column, extending its lifespan and ensuring the reproducibility of analysis results. As the usage time increases, the separation efficiency of the high-performance liquid chromatography column decreases and the column pressure increases. The main reason is that a small amount of packing in the inlet section of the chromatography column is contaminated, while the entire column bed is not damaged. Using a protective column is equivalent to adding an additional packing before the chromatography column, which protects the entire chromatography column.
Non direct connection protective column cover
The non directly connected protective column sleeve is connected to the analytical column through a section of pipeline and joint, and the traditional design can be matched with all HPLC columns.
Direct connected protective column cover
Direct coupled protective column cover is a convenient and reusable protective column cover that can be directly connected to the inlet of the chromatographic column. Hand tight direct coupling does not require other connecting pipelines, thus achieving excellent chromatographic performance.
characteristic:
Direct connection design does not require additional joints;
Quick and easy hand tight installation;
Convenient replacement of protective column core;
Universal direct connected protective column set
