Waters, 176003076, XSelect Peptide CSH C18 Method Validation Kit, 130Å, 2.5 µm, 4.6 mm X 100 mm, 1K - 15K, 3/pk

Waters CSH130 C18 based 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. Packed in ultra-low dispersion hardware, XSelect CSH130 C18 2.5 µm eXtended Performance [XP] columns enable exceptional separation performance, robustness and throughput for HPLC assays while enabling a seamless transition path toward UPLC adoption. This kit consists of three XSelect CSH130 C18 XP 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.
