ES Industries guard cartridge holders are designed for use with ES Industries guard column cartridges. Adding a guard column to your HPLC system extends the life of your column (up to 400%). When placed between the injector and the column, the guard column traps components that would otherwise irreversibly contaminate the stationary phase of the column, buffer against the effects of aggressive mobile phases and add capacity to your system to ensure no adverse chemical influence on sensitive separations.
Please Note: All guard cartridge holders must be used in conjunction with appropriately sized guard cartridges.
