QuEChERS EXTRACTION KITS

摘要

Adding solvent and salts to small (10g or 15g) comminuted fruit or vegetable sample enables you to extract the pesticides of interest into the organic layer. However, adding a food sample with high percentage of water directly to the salts may create an exothermic reaction that can affect your analyte recoveries. Choose the extraction salt packet based on your method of analysis, AOAC or EN. The buffered extraction salts are amenable for more liable pesticides.
