C18 Chromatography Silica Gel Powder 

silica gel powder

C18 reversed phase silica gel is widely used for separating and purifying peptides, antibiotics, and small natural molecules. It offers versatility for conventional chromatographic applications. The C18 AQ variant enhances retention and selectivity for polar compounds in 100% aqueous phases by controlling bonding density. Additionally, C18 Polar, with its amide polar functional groups, provides different selectivity for polar compounds compared to C18 AQ, while also being suitable for use in 100% aqueous phases. These characteristics make C18 silica gel a critical tool in various chromatographic processes.
