Determination of Pesticide Residues in Cannabis by LC-MS/MS (TN-1224)
The current Oregon pesticides guide/ list covers a range of pesticides with diverse chemical properties. When a suitable analytical method is developed using this list, it would be easy to include additional pesticides that may be necessary in different regions. The LC-MS/MS method detailed here makes use of sample prep dilution with reversed phase HPLC column chemistries with resolving power for the multiresidue pesticides of interest. Orthoganol Kinetex and Luna Omega column chemistries provide a complimentary selectivity as well as sensitivity for both standards in solvent and cannabis matrix. Sensitivity is achieved on two different triple quadrupole mass spectrometer platforms: SCIEX QTRAP 4500 and 6500+. The chromatography is demonstrated here on a SCIEX Triple Quad 3500 on abbreviated 50 mm length columns.
