Some applications of solid phase micro extraction (SPME) in the analysis of pesticide residues in food

Abstract

The Solid Phase Micro‐Extraction (SPME) technique was applied to analyze chlorpropham in potatoes and amitraz in honey. The homogenized sample, suspended in water and stirred, was extracted with a 100 μm thick polidimetylsiloxane fiber and desorbed into the injection port of a gas chromatograph/mass‐spectrometer (quadrupole) operating in single ion monitoring. Sensitivities down to 0.01 mg/Kg and linear responses in the range of 0.01–0.1 mg/Kg were obtained. The results of SPME pesticide residue analysis in potatoes corresponded to those obtained with a traditional multiresidue method.
