Quick, Easy, Cheap, Effective, Rugged, and Safe, the QuEChERS method is based on work done and published by Anastassiades et al. 1. QuEChERS was developed using an extraction method for pesticides in fruits and vegetables, coupled with a cleanup method
that removes sugars, lipids, organic acids, sterols, proteins, pigments, and excess water. This technique offers a user friendly alternative to traditional liquid liquid and solid phase extractions. The process involves two simple steps. First, the homogenized
samples are extracted and partitioned using an organic solvent and salt solution. Then, the supernatant is further extracted and cleaned using a dispersive solid phase extraction, dSPE technique. Restek products make this approach even simpler. We offer QuEChERS
extraction and dSPE products in a variety of standard sizes and formats. The dSPE centrifuge tube format, available in 2 mL and 15 mL sizes contains magnesium sulfate, to remove residual water and, primary secondary amine (PSA) sorbent, to remove sugars and
fatty acids. These tubes are available with or without graphitized carbon, to remove pigments and sterols and or C18 packing to remove nonpolar interferences, such as lipids.
