QuEChERS is a type of dispersive solid phase extraction (dSPE) used for sample preparation. QuEChERS stands for ‘Quick, Easy, Cheap, Effective, Rugged and Safe’. Originally developed to prepare fruit and vegetable samples for pesticide residue analysis, this method is now used to analyze other chemical classes, including PAHs (polycyclic aromatic hydrocarbons), PCBs (polychlorinated biphenyls), PBDEs (polybrominated diphenyl ethers), and flame retardants. The concept was introduced in 2002 and is now specified in official methods of the Association of Analytical Communities (AOAC 2007.01) and European Committee for Standardization (EN 15662:2008).
