Abstract
A simulation and optimization software program (Pro ezGC(R) by Analyti cal Innovations, Inc., Kettering, OH, USA) for GC temperature programs was applied to the analysis of organochlorine pesticides in sediments . By means of this software, the run time of a conventional temperatur e program derived from trial and error experiments could be reduced to less than a third, achieving at the same time an increased separation efficiency. Finally, 17 organochlorine pesticides could be baseline-r esolved on a capillary column in less than 12 min. In addition, a two- fold sensitivity enhancement was achieved.
