Determination of Pesticide Residues in Kale and Grapes using QuEChERS and LC-MS/MS (TN-0115)
Following the EN 15662 pesticide residue method using roQ™ QuEChERS extraction and clean-up dSPE kits, along with the use of a highly efficient and broad polarity Kinetex ® 5 μm Biphenyl Core-Shell HPLC column, a pesticide screening method was developed using LC-MS/MS in under 16 minutes. Over 200 pesticides were screened at concentration ranges between 0.01 ppm to 1 ppm with the majority of analytes having a recovery range of 70-130 %. The method produced excellent selectivity and reproducibility for the earlier eluting polar pesticides owing to the use of QuEChERS for removing sample matrix interferences and the biphenyl bonded-phase chemistry of the Kinetex Biphenyl column for the chromatographic separation across the entire range of pesticides.
