Waters XSelect Peptide CSH C18 Method Validation Kit, 130Å, 3.5 µm, 4.6 mm X 100 mm, 1K - 15K, 3/pk

Waters XSelect CSH130 C18 3.5 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 CSH130 C18 column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications. This kit includes three XSelect CSH130 C18 columns packed with three different batches of sorbent and one vial of Cytochrome C Digestion Standard (P/N 186006371. The standard is included to be able to immediately benchmark the column upon receipt and can be reordered as a separate part for continued monitoring. Each batch of digestion standard is prepared under strict quality control criteria confirmed on the included certificate of analysis.)
