Hamilton Company offers one of the most comprehensive selections of chromatography columns in the industry.

Each column is manufactured under rigorous criteria and tested for resolution and retention time accuracy. Hamilton guard columns protect your analytical HPLC column. They remove particulate contaminants and highly adsorptive compounds from samples, prolonging analytical column life. Guard columns are modular and cartridge replacement is easy and tool free. Guard column cartridge holders are available in stainless steel and PEEK materials, depending on the column. Both designs are optimized to reduce dead volume and prevent extra column band broadening.

Holders for the cartridges are reusable indefinitely. As with all guard columns these should be installed before the analytical column and after the injection valve.
