Answer:It protects a Discovery C18 analytical column from particulates and strongly retained sample components.
Discovery® C18 Supelguard Guard Cartridge Kit is used to protect Discovery C18 analytical columns from particulate matter and strongly retained sample components. The kit contains a 2 cm × 4 mm stainless-steel guard cartridge packed with 5 µm high-purity spherical silica carrying an endcapped C18 bonded phase with 180 Å pores. This phase matches the selectivity of Discovery C18 analytical columns and is suitable for reversed-phase HPLC. The short guard bed reduces contamination of the analytical column while adding minimal extra system volume. The kit includes one guard cartridge, a stand-alone holder, connecting tubing, and the required nuts and ferrules, allowing installation ahead of a compatible analytical column. This protective format is particularly useful for complex or dirty samples where extending analytical-column lifetime can reduce downtime and replacement cost.
