XSelect Premier Peptide CSH C18, OBD Prep Column, 3.5 µm, 10 mm x 100 mm (each batch specifically QC with complex protein digest) uses MaxPeak High Performance Surface (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 Peptide CSH130 C18, 5 µm particles contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape fora variety of molecular types using either FA- or TFA-containing mobile phases. The fact that the performance of a Peptide 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 Peptide OBD Preparative Columns enable exceptional separation performance, robustness and throughput for purification workflows while enabling seamless UPLC to Prep scaling.
