Direct Analysis of Polar Pesticides Without Derivatization

Mar 06 2018 Read 290 Times

One of the most in-demand workflows any food and environmental lab needs is a solid method for the analysis of polar pesticides. Here we present a collaborative method with Nofalab, Laboratories, Netherlands. This is a robust and sensitive method for the high throughput analysis of polar pesticides. The compounds found within this non-derivatized workflow are glyphosate, ethephon, glufosinate-n-acetyl, AMPA. glufosinate, 3-MPPA, phosphonic acid and chlorate. Also included are MRM transitions for the appropriate internal standards.

This study explores the performance of this method in:

  • Fruit and Vegetables
  • Seeds
  • Vegetable oil, Fat and Fatty Acids
  • Grain
  • Herbs and spices
  • Meat and Seafood
  • Animal Oil, Fat and Fatty Acids
  • Eggs and Eggs products
  • Milk and Milk products
  • Fatty acids
  • Drinking Water

This ion chromatographic approach to the analysis of polar pesticides offers the ability to include multiple analytes in a single injection without derivatization. By deviating from traditional LC buffers on the SCIEX QTRAP® 6500+ mass spectrometer, the analysis is performed using a standard reverse-phase LC based system, without the use of an ion suppressor
