Fig. 7From: Organic polymer monolithic columns with incorporated bare and cyano-modified fumed silica nanoparticles for use in hydrophilic interaction liquid chromatographyChromatograms of small neutral polar solutes (a), nucleobases (b), and organic acids (c) obtained on 0.6 mg of CN-FSNPs/cm-poly(GMM-co-EDMA) column. For a, b, and c, the conditions and the order of solute elution are the same as in Figs. 2a, b, and c, respectivelyBack to article page
