QuEChERS (an acronym for Quick, Easy, Cheap, Effective, Rugged, and Safe) is a commonly used sample preparation technique that is employed in most multi-residue pesticide testing laboratories.

In residue testing, the primary challenge is to eliminate naturally occurring pigments, fats, waxes, and other unwanted interferences from the sample matrix in order to achieve lower limits of detection and quantification of pesticides. Traditional techniques using liquid/liquid extraction employed the use of hazardous solvents, and suffer from poor recoveries for polar pesticides.

The QuEChERS method has proved to be extremely versatile for simultaneous analysis of multiple classes of pesticides from various matrices. The large variety of food matrices, ranging from aqueous, fiber rich, to fat/oil based foods can undergo a relatively simple cleanup using different sorbent mixtures and a single technique.
