ACQUITY UPLC Peptide BEH Columns

ACQUITY UPLC Peptide BEH C18, 130Å or 300Å Columns offer a wide usable pH range and outstanding temperature stability for applications ranging from proteomics to peptide mapping. ACQUITY UPLC CSH C18, 130Å Peptide Columns with a low-positive charged surface can be used with standard TFA-containing eluents or with a weaker acid modifier such as formic acid, eliminating the need to compromise between a reversed-phase eluent that delivers sharp peaks or one that minimizes reduction of the MS signal.
