HPLC Column MV Kit XSelect Peptide CSH C18 130Å, 3.5 µm, 2.1x100 mm, 3/pkg, L1, 1 - 11 Ph Range, Low Silanol Activity, 185 m2/g, End Capped, Spherical, 15 % Carbon Load

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.
