HPLC Guard Columns

Guard columns are protective columns that is installed between the injector and the analytical column. Guard columns have two main functions. The first is to trap particulate matter that would otherwise block the column through a frit at the inlet. They also utilize packing material that is matched to the analytical column to trap materials that would become strongly or irreversibly bound to the analytical column.

Guard columns often match the phase of the analytical column to protect the analytical column from irreversibly bonded compounds. For more product offerings, please visit our LC Columns page, where you will find analytical columns and matching guard columns.
