HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column BR-C18, Guard cartridge with holder, 3 µm, 120 Å, 4 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, BR-C18 bonded phases have been innovatively and specially designed to ensure maximum surface coverage and full end-capping, which leads to carbon content as high as 19.0%. The bonding chemistry is completely controlled that results in very reliable column-to-column reproducibility. The maximum surface coverage allows BR-C18 to have exceptional stability, resulting in high pH stability in the range of 1.5 to 10.5.
