QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample preparation approach involves liquid-liquid partitioning using acetonitrile and purifying the extract using dispersive solid-phase extraction (d-SPE). Originally the QuEChERS was introduced for pesticides residues analysis in high moisture fruits and vegetables but more recently it is gaining significant popularity in the analysis of broad spectrum of matrices and analytes like: veterinary drugs and other pharmaceuticals, mycotoxins, polycyclic aromatic hydrocarbons (PAHs), dyes, acrylamide, synthetic musks and UV filters, bisphenols, polybrominated diphenyl ethers and other flame retardants, endocrine disruptors and other chemical compounds. The wide range of the technique applications is possible due to introducing various modifications based on the use of different extraction solvent and salt formulation and buffer additions for salting-out partitioning step and the application of various d-SPE sorbents for clean-up step. Nowadays the most used protocols are the EN15662 and AOAC2007.1 Qtube QuEChERS kits - are available in practical pouches for the extraction phase and in 15 ml and 2 ml tubes for the clean-up.
