Summary:In this paper a method for the determination of plasticisers in food by gas chromatography-mass spectrometry with ion-trap mass detection is described. The plasticisers were quantified by an internal standard addition method using diisobutyl phthalate as the internal standard. Four selected food samples were spiked with nine different plasticisers at about 0.3 μg/g. The recoveries of the plasticisers were in the range of 90 to 106%. The proposed method shows an improvement in precision and exhibits good linearity over a wide concentration range. The new method was applied to the analysis of real samples and the results were found to agree with those obtained using the well-established isotope dilution technique.
