“Personal Care Formulation & Characterization”.
The purpose of this step is to extract pesticide residues into an organic solvent. A solid-liquid extraction with addition of salts to control pH and ionic concentration is performed.
QuEChERS, USER-FRIENDLY standing for Quick, Easy, Cheap, Effective, Rugged, and Safe is readily accepted by both the Association of Analytical Communities (AOAC) and the Committee of European Normalization (CEN) for the analysis of pesticide residues in food and agricultural products.
QuEChERS is a simple and straightforward sample preparation technique for multi-residues screening. Multi-residue methods increase sample throughput, decrease sample turnaround time, and optimize analyst efficiency. The QuEChERS method is a two-step process: clean up followed by extraction.
