Guard Column Cartridges, NP Silica Wide Pore, 10um, 300A. 4.0mm ID x 10mm Length. Cogent Brand. 5/PK.
Additional Information:
Cogent NP Silica™ Wide Pore Guard Column Cartridges are designed to protect valuable analytical HPLC columns from particulate matter, strongly retained contaminants, and sample matrix components that can shorten column life and reduce chromatographic performance. Packed with ultra-high purity, low metal content, 300Å NP Silica™ Wide Pore that remains completely unmodified, these cartridges provide the same chromatographic selectivity as the analytical column they protect while helping maintain method reproducibility and chromatographic efficiency.
82061-PG2-3 is packed with 10 µm NP Silica™ Wide Pore particles in a 4.0 mm ID x 10 mm guard cartridge format. The 300Å pore structure provides improved accessibility for proteins, peptides, biomolecules, and other large molecular weight compounds. Designed for use with 3.0 mm, 4.0 mm, and 4.6 mm ID NP Silica™ analytical columns, these guard cartridges are housed in stainless steel tubes with stainless steel frits pressed into durable PEEK frit caps for dependable operation and column protection.
Regular guard cartridge replacement can significantly reduce operating costs while protecting valuable analytical columns used in HILIC and Normal Phase chromatography. These guard cartridges are particularly beneficial when analyzing complex biological, pharmaceutical, and research samples where contaminants and strongly retained compounds can adversely affect column performance and longevity.
