AOAC method
QuEChERS is a sample preparation method proposed by Anastassiades in 2003. It is now widely used in food, environmental water samples, and soil contaminants; Refer to the AOAC Standard (AOAC Official Method 2007.01 Pesticide Residues in Foods by Acetonitrile Extraction and Partitioning with Magnesium Sulfate), and select QuEChERS according to different samples.
