Guard Column Cartridges, NP Amino, 5um, 100A. 2.1mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent NP Amino™ Guard Column Cartridges are designed to protect valuable analytical HPLC columns from particulate contamination and strongly retained compounds that can reduce column performance and shorten column life. Packed with the same NP Amino™ stationary phase as the corresponding analytical columns, these guard cartridges help maintain chromatographic performance while reducing replacement costs and instrument downtime.
68540-PG1 is packed with 5 µm NP Amino™ particles in a 2.1 mm ID x 10 mm guard cartridge format with a 100Å pore size. Manufactured using a three-carbon propyl ligand containing a terminal amino functional group bonded to the highest purity silica available, this stationary phase is not end capped and provides the same selectivity characteristics as Cogent NP Amino™ analytical columns. Each cartridge is packed in a stainless steel tube and fitted with stainless steel frits pressed into durable PEEK frit caps for reliable performance.
Designed specifically for use with 2.1 mm ID NP Amino™ analytical columns, these guard cartridges help prevent contamination from sample particulates and strongly adsorbed compounds before they reach the analytical column. They are particularly beneficial for HILIC and Normal Phase separations involving sugars, compounds containing carboxylic acid groups, and other highly polar analytes.
