U(H)PLC Column ACQUITY Premier PST CSH C18, 130 Å, 1.7 µm, 2.1 x 50 mm, 18000 psi

Quality controlled with peptide standards for the analysis of peptides, Waters ACQUITY PREMIER CSH130 C18 1.7 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 column is part of the PREMIER class of columns, which deliver the chromatographic performance expected from our particle technologies while increasing reproducibility, peak shape, and recovery for metal-sensitive analytes.
