Resolve polar and nonpolar compounds in a single run with Thermo Scientific™ Acclaim™ PolarAdvantage II (PA2) reversed-phase columns. These high-efficiency, silica-based columns have a polar-embedded stationary phase that operates over a wider range of chromatographic conditions than possible with conventional reversed-phase stationary phases. Its unique chemistry provides enhanced hydrolytic stability from pH 1.5 to 10 with 100% aqueous mobile phases. The column exhibits selectivity that is complementary to conventional C18 columns and excellent peak shapes for both basic and acidic compounds.
