Agilent, PL1310-0016, Guard Cartridge Holder for 3.0 x 5 mm cartridges (PL)

The Agilent Hi-Plex Guard Cartridge Holder is a reusable mounting component for compatible 3.0 × 5.0 mm guard cartridges. It provides the mechanical interface needed to position a short protective cartridge in the liquid chromatography flow path ahead of the analytical column. Correct holder assembly supports fluid containment and low-dead-volume transfer between the inlet tubing, guard element and primary column. Choose a cartridge with stationary-phase chemistry appropriate to the analytical method, then assemble the holder with the correct orientation and fitting geometry. Inspect contact surfaces for residue and damage whenever a guard element is changed. Tighten connections using the prescribed hardware procedure rather than excessive force that could deform fittings or cartridge components. After assembly, flush with a method-compatible liquid and inspect for leaks before injecting samples. The holder has no intrinsic calcium ion-exchange resin, so it cannot separate carbohydrates on its own. This is the hardware accessory, not a prepacked guard cartridge or a full analytical Hi-Plex LC column.
