I. DuPont de Numours and Co., Inc. Keith Tucker, SPEX SamplePrep, LLC Robert Thomas, Scientific Solutions Summary The high-throughput analysis of pesticides has been hindered by the slow and laborious sample preparation stage. Using traditional clean-up procedures, over twenty steps are required to get the sample in a convenient form for analysis, which limits sample throughput to typically 8 samples per day. This study evaluates a new approach using an innovative laboratory tissue homogenizer, to extract various pesticide residues from different kinds of plant materials and to identify and quantitate the active ingredients by LC/MS/MS. It shows that by automating the sample preparation procedure, the number of clean-up steps can be significantly reduced, resulting in an increased sample throughput over traditional approach
