Waters, 186009904, XSelect Premier Peptide CSH C18 Column, 130 Å, 2.5 µm, 2.1 x 50 mm, 1/pk

The first choice for peptide separations, Waters XSelect Premier Peptide CSH C18 Column, 130Å, 2.5 µm, 2.1 x 50 mm 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. Quality controlled with cytochrome c digest standards (p/n: 186006371) for the analysis of peptides. The fact that the performance of an XSelect Premier Peptide CSH C18 Column, 130Å, 2.5 µm, 2.1 x 50 mm Column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications. 2.1mm ID columns are recommended for use with low dispersion (UPLC or UHPLC) systems, especially for LC-MS methods. This column is part of the MaxPeak 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. Suggested Use: Peptide Separations, Peptide Analysis, Peptide Mapping, Synthetic Peptides

Additional Information
XSelect Premier Peptide CSH C18 Column, 130Å, 2.5 µm, 2.1 x 50 mm, 1/pk The right protein HPLC column for your complicated protein separations and analysis is finally here with the new XSelect Premier Peptide CSH C18 Column. Not only is this product tested using official peptide standards to ensure superior performance, it also comes equipped with MaxPeak High Performance Surface Technology to prevent any unwanted secondary interactions while you’re in the lab. Plus, the XSelect Premier Peptide CSH C18 Column comes equipped with features to help you overcome the obstacles inherent in protein purification by HPLC, including the concern about lack of scalablity. Practical approaches for peptide isolation also present a series of obstacles for an experienced scientist to overcome. That’s why we’re happy to present a protein HPLC column that provides a stable surface chemistry adaptable to most peptides. The CSH (Charged Surface Hybrid) technology helps to enable that stable surface chemistry, while MaxPeak HPS ensures you have the peak shape you want out of your demanding assays. Also, thanks to this column’s low dependency on strong ion-pairing agents to function at peak performance, getting reproducible results is easier than ever. Peptide separation by HPLC requires a unique tool that can overcome difficult sample prep and other factors that can lead to undesirable results. That’s why Waters scientists put their heads together to create the XSelect Premier Peptide CSH C18 Column, which yields comparatively excellent peak shape for peptide isolation and separation using formic acid or non-formic acid mobile phases. Get the chromatographic performance your lab so rightly deserves with this column. Curious about the XSelect Premier Column family? These HPLC columns were designed to provide the selectivity you need during LC method development without the factors you don’t, like losses in peak shape or signal intensity. This even helps to minimize variability, one of the many challenges presented in method development. And if your concern is about unwanted analyte-surface interactions, know that the MaxPeak HPS feature is more than capable of handling that. Shop XSelect Premier Columns to find the right match for your LC-MS needs today. At Waters, it’s our goal to deliver benefit by designing and providing products that make the life of scientists better and their labs more efficient.
