QuEChERS extraction kits
Step 1: Extraction
Choose the extraction salt packet based on your method of analysis, AOAC or EN. The buffered extraction salts are amenable for more liable pesticides. Adding solvent and then salts to a comminuted fruit or vegetable sample (10 g or 15 g) enables you to extract the pesticides of interest into the organic layer. However, adding a food sample with a high percentage of water directly to the salts may create an exothermic reaction that can affect your analyte recoveries.
- Available with or without 50 ml centrifuge tubes and caps
- Include MgSO₄, NaCl, or other salts for buffering; pre-weighed in anhydrous packet
QuEChERS salts and buffers are packaged in anhydrous packages. This allows you to add them after adding your solvent to the sample, as specified in QuEChERS methodologies.
