Liquid Chromatography Columns – SciSil

Traditional silica synthesis cannot remove a large amount of metal impurities. As a result, when analyzing basic compounds or compounds prone to chelation, significant tailing occurs, and samples may be adsorbed by the stationary phase. SciSil uses Type B silica gel, prepared from Si(OC2H5)4, which contains virtually no metal impurities. Therefore, it is recommended to choose Type B silica gel columns when selecting chromatography columns.

SciSil employs a special surface coverage technology, where C18 bonded phases are interconnected on the silica surface. This ensures extended column lifetime even under strong acidic or basic mobile phase conditions.

• High-purity silica gel, metal impurities <5 ppm

• Wide pH range, fully compatible with pH 1.5–10.5

• Consistent reproducibility across different batches

• Long service life
