Waters, 186007019, XSelect Peptide CSH C18 Guard Column, 130Å, 5 µm, 19 mm X 10 mm, 1K - 15K, 1/pk

Waters XSelect CSH130 C18 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
