- Abstract
An efficient and precise method utilizing ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)was developed to quantify fipronil and its metabolites in eggs. The extraction of samples was performed using acetonitrile, followed by solid phase extraction column cleanup to prepare them for UPLC-MS/MS analysis. The results showed good separation, and that the average recovery of fipronil and its metabolites at 0.005,0.010 mg/kg and 0.020 mg/kg was between 81.3% and 92.5%,and the relative standard deviations were below 5.5%. Significant linear correlations were found between the peak area and the concentration of fipronil and its metabolites within the range of 0.001-0.050 μg/mL, with correlation coefficients surpassing 0.990.4. The limit of detection of fipronil, fipronil-desulfinyl, fipronil-sulfide, and fipronilsulfone was 0.001,0.002,0.002 mg/kg and 0.002 mg/kg, respectively. The UPLC-MS/MS method was accurate, sensitive and rapid and can detect fipronil and its metabolites in eggs.
