[Validation study on a multi-residue method for determination of pesticide residues in agricultural products by new automatic pretreatment equipment (FASRAC) and GC-MS/MS].

A validation study was performed on a multiresidue method for determination of pesticide residues in agricultural products according to the method validation guideline of the Ministry of Health, Labour and Welfare of Japan. FASRAC (Food Automatic Analytical Systems for Residual Agricultural Chemicals) automatically performs extraction of pesticide residues from agricultural products with acetonitrile, filtration, constant volume, mixing with the use of air, mixing acetonitrile with buffer solvent, separation, and dehydration with sodium sulfate. The extract was purified with a GC/NH2 column.
