The “columns” in HPLC are the analytical HPLC column, guard column, Proecolumn, etc. Precolumn and Guard Columns are used to protect the analytical HPLC column. The terms Proecolumn and Guardcolumn are sometimes mixed. The terms treated and guard columns are sometimes combined, so they are distinguished here. The terminology is sometimes confused and is explained here.

What is the difference between a Proecolumn and a guard column?
A Proecolumn is positioned between the pump and the injector and only passes through the mobile phase. The guard column is positioned between the injector and the analytical column, passing through the mobile phase and sample solution.

Guard column for UHPLC significantly extends column lifetime of your analytical column. The replacement cartridge guard column can be exchanged easily. A 1/16 inch tube is connected at the outlet of the holder for easy installation with minimized dead volume.
