Pesticides
Printer Friendly VersionPesticides, Herbicides, Insecticides, Fungicides Analysis
Brief Description:
Pesticides/herbicides/insecticides/fungicides can be detected in extracted plant tissues (leaf, root, shoot), pollen, soil, water, or tissues. Samples are typically prepared using an established QuEChERS protocol which varies depending on the type of material you wish to analyze and the pesticides you wish to evaluate. The prepared samples are separated on an Agilent Zorbax SB-phenyl HPLC column and detected using our Agilent 6460 triple quadrupole mass spectrometer in MRM mode. The run time is approximately 15-30 minutes per sample, depending on the number of pesticides you wish to acquire data for in the assay. We can quantify as little as one pesticide or perform a comprehensive assay in which we acquire data for >65 different pesticides. Data are collected in positive or negative electrospray ionization modes. Data are typically normalized to wet tissue weight or sample volume if liquid.
Normal Weight: Tissue (0.2-5 g); water (10-100 mL); soil (1-5g dry)
Minimal Weight: Tissue (0.1-0.2 g); water (1 mL); soil (0.5g dry)
Special Handling: Samples should remain frozen at -80°C and in darkness prior to analysis if possible
