The ZORBAX High Performance Guard Cartridge series has been developed to provide convenient, cost-effective protection for high performance analytical columns. The cartridge components assemble quickly and easily to provide a high efficiency, low-dead-volume column that seals, with hand tightening, up to 5000 psi (340 bar) or 3000 psi with a PEEK fitting.
The reusable guard column end fitting with integrated 1/16-inch OD tubing adapts the cartridge guard column for direct connection to standard 1/16-inch LC fittings and provides a stand-alone guard column system for 2.1-4.6 mm ID columns. There are two different end-fitting options to allow the use of other connecting tubing.
The polymeric guard cartridges used in this holder are specifically designed to make leak-tight seals against metal surface without requiring gaskets. This polymeric material (polyphenylenesulfone) is also more solvent-resistant than PEEK.
Guard cartridges are available for almost every ZORBAX bonded phase and can be found in the ordering information for each type of column.
