"The first choice for peptide separations, Waters XSelect Premier Peptide CSH C18 Column, 130Å, 2.5 µm, 4.6 x 150 mm 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. Quality controlled with cytochrome c digest standards (p/n: 186006371) for the analysis of peptides. The fact that the performance of an XSelect Premier Peptide CSH C18 Column, 130Å, 2.5 µm, 4.6 x 150 mm Column exhibits little dependence on strong ion pairing agents makes it ideal for LC 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. Suggested Use: Peptide Separations, Peptide Analysis, Synthetic Peptides. This column comes equipped with an electronic eConnect column tag containing unique column-specific information. These NFC-enabled device-tagged columns were developed to automatically identify, track and digitally trace column use history. eConnect columns can be used on any HPLC, but its advantages are unlocked when used with the Waters Alliance iS and Alliance iS Bio System running Empower software."
