Аннотация:Correlation coefficients were considered for various combinations of analytical parameters for a series of 20 most widely used pesticides. These parameters included gas-chromatographic retention indices (RIs) on standard nonpolar polydimethylsiloxane stationary phases, RIs in reversed-phase HPLC, data on out-of-column phase equilibria (distribution constants K-p in heterophase solvent systems), UV-spectroscopic characteristics, and the most important mass-spectrometric characteristics. A combination of RIs with the relative absorbance A(rel) = A(254)/A(220) and distribution constants in the hexane-acetonitrile system was found to be most informative for the HPLC identification of compounds from this class.
