Abstract
Supercritical fluid extraction was used to extract pesticides from cereals. Each sample was homogenized with water, celite, and
water-absorbent polymer. The obtained mixture was extracted using supercritical carbon dioxide. Each pesticide trapped in ODS
column was eluted by acetonitrile and was analyzed using LC-MS/MS. The validation study (2 samples per day on 5 days) was
conducted for 114 compounds at 0.01 and 0.05 μg/g for 5 samples. Results demonstrated that 47–71 compounds in each sample met
target values for trueness, repeatability, and within-laboratory reproducibility. This assay can be used as a method for analysis of
pesticide residues in cereals.
