XSelect Premier Peptide CSH 130A C18

Quality controlled with peptide standards for the analysis of peptides, Waters XSelect Premier Peptide CSH, C18, 130Å, 2.5 µm particles contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape for peptides using either FA- or TFA-containing mobile phases. The fact that the performance of an XSelect Premier Peptide CSH, C18, 130Å, 2.5 µm Column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications. This column is part of the MaxPeak Premier Class of Columns, which deliver the chromatographic performance expected from our particle technologies while increasing reproducibility, peak shape, and recovery for metal-sensitive analytes.
