SH-GP-2 Guard Column

The SH-GP-2 Guard Column is specifically designed to protect analytical columns in ion chromatography systems by filtering out particulates, organic residues, and strongly retained compounds that may degrade the analytical performance or reduce column lifespan. It acts as a sacrificial layer, ensuring the main analytical column maintains its separation efficiency over extended use. Compatible with various SH-series analytical columns (e.g., SH-AP-3, SH-AP-4, SH-AC-25), the SH-GP-2 features the same high-quality stationary phase as the main column, ensuring seamless retention characteristics without affecting analytical results.

Feature of SH-GP-2 Guard Column

• Protects analytical columns from contaminants and matrix residues

• Extends column lifespan by reducing fouling and back pressure

• Matched stationary phase ensures no interference with target analytes

• Compact design minimizes system dead volume

• Easy replacement with standard IC column fittings

• Universal compatibility with most IC systems (Dionex™, Metrohm™, Shimadzu™, CIC, etc.)
