HPLC Guard Columns

Precolumns (guard columns) and precolumn cartridges for HPLC

Separation columns with modern solid phases are critical components of the HPLC system. Careful handling and protection against impurities is necessary to ensure optimum and consistent separation results. In order to extend the life of your HPLC columns, it is advisable to use guard columns. They are able to remove molecules which would form an irreversible bond with the material of the analytical column. Guard coloumns need to be changed on a regular basis. A good indication on when to change a precolumn is a gradual increase in the back pressure. For more information on the storage and maintenance of HPLC column, click here.
