Catalog Number - 68040-SP-PG1

Cogent NP Amino Semi Prep Guard Column Cartridges are packed with the same propyl amino bonded stationary phase used in Cogent NP Amino semi-preparative columns. Manufactured on high-purity silica with an amino-functionalized propyl ligand, these guard cartridges protect the semi-preparative column from particulates, strongly retained contaminants, and sample matrix components that can reduce chromatographic performance and shorten column life. The chemistry is suitable for both Normal Phase and HILIC applications and provides the same USP L8 selectivity as the semi-preparative column it protects.

68040-SP-PG1 is a semi-preparative guard column cartridge packed with 10 µm NP Amino particles featuring a 100 Å pore size in a 10 mm ID x 10 mm format. Installed ahead of the semi-preparative column, it captures contaminants before they reach the analytical bed, helping maintain chromatographic efficiency, improve reproducibility, and extend column lifetime in demanding purification applications.

These guard cartridges are specifically designed for use with 10 mm ID Cogent NP Amino Semi Prep Columns and are housed in durable stainless-steel hardware with stainless-steel frits for reliable operation under semi-preparative flow conditions.
