Abstract/OtherAbstract:
Three environmentally friendly extraction techniques, membrane assisted solvent extraction (MASE), stir bar sorptive extraction (SBSE), and headspace solid phase microextraction (HS-SPME), were compared for the direct analysis of the highly toxic rodenticide tetramine in food. The optimized MASE method was applied to seven foods fortified with tetramine and compared to previously reported SBSE and HS-SPME results. Parameters such as the standard addition linearity (MASE (0.964-0.999), SBSE (0.966-0.999), HS-SPME (0.955-0.999)), recovery (MASE (12-86%), SBSE (36-130%), HS-SPME (50-200%)), reproducibility (MASE (3.0-30%), SBSE (4.4-9.6%), HS-SPME (1-12%)), and LOD (MASE (1.6-6.4 ng/g), SBSE (0.2-2.1 ng/g), HS-SPME (0.9-4.3 ng/g)) were compared.
