Brand: Thermo Fisher Scientific

HyPURITY C18 HPLC column with 4.6 mm inner diameter, 250 mm length and 5.0 µm particle size. About HyPURITY AQUASTAR Columns Thermo Scientific HyPURITY AQUASTAR columns are a silica-based polar end-cappedC18 that is designed to offer superior retention of polar compounds and increased sensitivity in 100% aqueous conditions. The robust nature of the bonded phase makes the column ideal for HPLC and LC/MS applications. This column also offers unmatched batch reproducibility over previous polar end-capped columns. Increased Polar Analyte Retention Dispersive interactions are the primary mechanism of retention in traditional alkyl chain columns. Secondary interactions are usually associated with residual silanols and can be reduced by the use of end-capping, high purity silica and increased density of the derivatized ligand. With HyPURITY AQUASTAR columns, dispersive interactions are reduced but still play a major role in retention of both polar and nonΕμφάνιση περισσότερων
