QuEChERS Dispersive SPE Product Selection

The QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) technique is increasingly becoming the technique of choice for extraction and clean-up of pesticide residues. It was developed by the USDA
Eastern Regional Research Center. Please refer to the information below for selection of the most
appropriate QuEChERS product for multi-residue pesticide analysis.

There are four variations of the QuEChERS method currently being used:

  • The original QuEChERS method – this was introduced in 2003, using sodium chloride to enhance extraction

 

  • Dispersive AOAC 2007.01 – this uses sodium acetate as a buffer, replacing sodium chloride

 

  • The dual phase variation – this method introduces the use of PSA and GCB to remove high levels of chlorophyll and plant sterols in the   nal extract without the loss of planar pesticides (polar aromatics) using an acetone:toluene solvent mix (3:1)

 

  •  The European version is similar to the AOAC method, except the extraction uses sodium chloride, sodium citrate dihydrate and disodium citrate sesquihydrate instead of sodium acetate
