Erik Beristain-Montiel

Hi, I have worked with pesticides for several years, so, regarding your question, Which is your matrix? The best way to extract them depends on the matrix; however, always you can perform an experiment design to test several conditions in few experiments to construct a model which show you the best conditions. The ideal conditions depends on which pesticides are you looking for. You can review my profile and there is a paper explaining about a experimental design and GC/MS conditions for the extraction and analysis of organochlorine pesticides:

If you need more specific help, do not hesitate in ask me.
