The retention order of methylated lysine and arginine derivatives followed a reversed-phase separation pattern on various silicas with aqueous salt solutions used as eluents. Principal component analysis established that the origin of the silica exerts a dominant influence on their chromatographic performance, and the effect of impregnation and salt quality are of secondary importance. Good linear correlations were found between the lipophilicity-decreasing effect of monovalent cations and their ionic radii.
