FAQ
How do Cortecs Pre-Columns protect LC Columns from chemical contaminants? One of the primary functions of Cortecs Pre-Columns is to condition the mobile phase before it reaches the sample and the column. Mobile phases can cause harm to the main column by degrading the high quality packing material. The pre-column is able to saturate the mobile phase with special packing that will protect the main columns particle substrate.
