General description

The Ascentis® Express biphenyl phase chemistry offers alternative selectivity for pharmaceutical analytes and drug metabolites that are not well retained or difficult to resolve on traditional alkyl (C18) and phenyl bonded phases. Ascentis Express HPLC columns, through the use of Fused-Core® particle technology, can provide you with both the high speed and high efficiencies of sub-2 ?m particles while maintaining lower backpressures. The combination of high efficiency and low backpressure benefits UHPLC users, as well as conventional HPLC users. Visit the Ascentis Express home page for more information on this new column technology.
