Answer:Each guard cartridge is 3.0 mm ID × 10 mm long.
Answer:The cartridge uses 5 µm Hypersil BDS C18 material.
Answer:The package contains four guard cartridges.
Hypersil™ BDS C18 guard cartridges protect compatible analytical columns from particulate contamination and strongly retained sample components. This configuration uses the same 5 µm base-deactivated C18 chemistry as the analytical Hypersil BDS C18 phase in a 3.0 × 10 mm cartridge and is supplied as a pack of four. Matching stationary-phase chemistry helps preserve method selectivity while allowing the inexpensive guard element to capture contaminants before they reach the main column. The cartridge format is useful for extending analytical-column service life in pharmaceutical, food, environmental, and general QC workflows. A compatible guard cartridge holder is required for installation.
