Abstract:Summary A computer-assisted method is presented for mobile phase selection for the optimal separation of pesticides by HPTLC and HPLC. The system is based on a plot of solute retention value and separation criterion vs. binary mobile phase composition for graphic optimization. The result of HPTLC can be transposed to HPLC for optimal separation. The transposition equation is given.
Keywords:Thin-layer chromatography  Column liquid chromatography  Mobile phase optimization  HPTLC transposition to HPLC
