XSelect Premier CSH C18, 130 Å, OBD Prep Column, 5 µm, 19 mm x 50 mm, 1/pk

XSelect Premier CSH C18, 130 Å, 5 µm, 19 mm x 50 mm, OBD preparative columns use MaxPeak High Performance Surfaces (HPS) hardware technology which significantly reduces unwanted analyte/surface interactions that can lead to poor peak shape and losses in signal intensity. These columns prevent undesired analyte/surface interactions through the power of MaxPeak HPS Technology, which is designed to increase analyte recovery, sensitivity, peak shape and reproducibility by minimizing analyte/surface interactions that can lead to sample losses. Waters XSelect CSH130 C18 5 µm particles contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape for a variety of molecular types 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 (UV-directed) purification or MS-directed purification. XSelect Premier OBD preparative columns enable exceptional separation performance, robustness and throughput for purification workflows while enabling seamless UPLC to Prep scaling.
