About this item
Hamilton guard columns protect your HPLC column.
- Guard columns are modular and cartridge replacement is easy and tool free
- The design is optimized to reduce dead volume and prevent extra column band broadening
As with all guard columns these should be installed before the analytical column and after the injection valve.
