DESCRIPTION
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 a 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.
