Chemometric characterization of the RF values of pesticides in thin-layer chromatography on silica with mobile phases comprising a weakly polar diluent and a polar modifier. Part IV

摘要

In addition to the fifty pesticides investigated in the first three parts of this study, in this paper plots of RF against modifier concentration, Cmod, are reported for chromatography of thirty-one moderately polar pesticides in systems of the type silica-heptane + modifier (ethyl acetate, tetrahydrofuran, and dioxane).
