LCTech - Determination of Pesticides in Fruits and Vegetables Automated with FREESTYLE QuEChERS and LC-MS/MS
QuEChERS has become the most important analytical method in routine pesticide labs for food and feed samples. The original QuEChERS set-up in brief consists of two main steps, the extraction and the clean-up step. Both of them are typically manually performed and use a dispersive approach, where two different buffer/salt and clean-up mixes are added to matrix solutions, respectively, with subsequent vortexing and centrifugation steps.
The aim of this application note is to show an automated approach for the second, the clean-up step in a non-dispersive way. Automation itself is a warrantor for highly precise processing with reduced deviation of analytical results even in sequences with a high sample number. Furthermore, using a non-dispersive approach, chromatography in general is better and unwanted matrix compounds or particles are retained on the top of the cartridge, thus leading to cleaner extracts with reduced matrix suppression in the LC-MS/MS measurement.
