Trace Analysis of Pesticides in High Matrix Samples Using GCxGC-qMS

摘要：

One of the most important problems in pesticide analysis is how to remove matrix interferences in the sample, which may hide small amounts of analytes and cause errors in identification of pesticides. Several approaches have been developed to deal with matrix interference: (1) chemically removing matrix interferences with skillful sample preparation, (2) optimizing quantitation and reference masses in GC/MS analysis, (3) selecting the appropriate ionization method in GC/MS analysis or selection of a suitable detector in GC analysis according to the type of target pesticides. Despite considerable efforts, separation of pesticides from matrix interferences is insufficient; analysis of pesticides in samples with complex matrices in a simple way and with high sensitivity is still in demand.
