Standard precolumns
Precolumns are available in 2 cm and 5 cm lengths. Both lengths are used in conjunction with a column end fitting. They can be used as analytical columns, but a more typical use is as a guard column installed between the injector and the analytical column.
Fingertight HPLC cartridge precolumns
This cartridge-based system is designed for use as a precolumn or concentrator column in HPLC and FIA applications. With replaceable snap-on seals and reusable cartridge, it is particularly suited to applications requiring frequent changes.
