The computer-assisted simulation program DryLab has been used to simulate TLC separations. The simulations were based on data from preliminary TLC separations. For DryLab data entry RF values from TLC were converted to retention times, the development distance on the plate was used as column length, and the plate thickness was used as the column diameter. To achieve reasonably accurate simulations it was found necessary to run three preliminary runs in which differences between organic modifier concentration in two adjacent runs was more than 5%. The possibility of predicting HPLC separation on the basis of TLC separations was also studied. It was found that the method can be transferred from TLC to HPLC and that DryLab can be used to predict HPLC separation on the basis of the information obtained from TLC experiments. To produce a reasonably accurate HPLC simulation on the basis of TLC data, however, a relatively large number of preliminary experiments is required.
