We recommend the use of a guard cartridge, in order to protect the analytical column from impurities with high affinity and particulate impurities. The guard cartridge should be replaced regularly; otherwise the column performance can be affected. This is of special importance in bioanalysis.).

In order to optimize the performance of the chromatographic system, the guard cartridge should have a dimension that matches the dimension of the analytical column

Protein-Protection Guard Columns for Chiral Analytical Columns Models

※ The connecting line between the guard column and the analytical column must be purchased by itself.
