The ZORBAX Preparative Guard-Column has been developed to provide convenient, cost-effective protection for high-performance lab-scale semipreparative columns. The cartridge components assemble quickly and easily to provide a high-efficiency, low-dead-volume column that seals at pressures up to 2000 psi (135 bar, 13.5 MPa).
The guard-column tubing made from polyphenylene sulfone is specifically engineered to make leak-tight seals against metal surfaces, without requiring gaskets. The reusable guard-column end fittings adapt the cartridge guard-column for connection to standard 1/16 in. LC fittings and provide a stand-alone guard-column system. The ZORBAX materials used in preparative cartridges are matched with chemistry chosen for compatibility with a wide range of applications.
