Case Study

Using Fipronil-¹³C₂ ¹⁵N₂ to Determine Fipronil and Its Metabolites in Seafood

Zhang, Yun, et al. Analytical methods 10.15 (2018): 1673-1679.

Accurately weigh 2.0 g of homogenized sample into a 10 mL polypropylene centrifuge tube, then add 20 µL of 1.0 mg/L fipronil-¹³C₂ ¹⁵N₂ and 4.0 mL of acetonitrile. Vortex the tube vigorously for 10 minutes to ensure better interaction between the solvent and the sample, then centrifuge at 10,000 g for 3 minutes. Collect the supernatant and transfer it to a new 10 mL polypropylene tube. Extract the residue again with 4 mL of acetonitrile, then centrifuge. Finally, combine the supernatants and dilute with acetonitrile to achieve a final volume of 10 mL for further cleanup procedures.
Analytical Performance
Spike fipronil-¹³C₂ ¹⁵N₂ (2.0 µg/L) into blank fish samples and construct a calibration curve with concentration ranges for fipronil, fipronil sulfide, and fipronil sulfone of 0.05-10.0 µg/L, and for fipronil desulfinyl of 0.20-50.0 µg/L. The linearity for all analytes was found to be adequate, with determination coefficients (R²) greater than 0.9991. The limits of quantification (LOQ) for fipronil, fipronil sulfide, and fipronil sulfone were 0.40 µg/kg each, and for fipronil desulfinyl, it was 2.0 µg/kg. The method exhibited good precision, with relative errors (RE) less than 12.5%, and intra-day and inter-day relative standard deviations (RSD) less than 11.4%. Recovery rates for fipronil and its metabolites at three levels of spiking were between 87.5% and 110%.
