The extractions are first processed using acetone, and one portion of the acetone solution undergoes a rapid liquid-liquid extraction for the polar pesticides, such as organophospates and organo-nitrogen pesticides.  The 2nd portion of acetone is processed using reversed phase mechanisms with DPX tips. The time-consuming column chromatography in the Luke Method for GC-ECD analysis of organochlorine pesticides is not required. The DPX extracts result in chromatograms that have low background interferences for a wide variety of fruit and vegetables. In fact, the ECD chromatograms obtained by using DPX are comparable to those obtained by the Luke Method.
