ABSTRACT

A new confirmatory method for simultaneous determination of bisphenol diglycidyl ether residues (BADGE, BADGE.H(2)O, BADGE.2H(2)O, BADGE.H(2)O.HCl, BADGE.HCl, BADGE.2HCl, BFDGE and BFDGE.2HCl) from canned food has been developed. The proposed method includes extraction by pressurized liquid extraction (PLE) followed by liquid-liquid partition and purification by solid phase extraction (SPE). Several solvent systems and different operating conditions (time, temperature) have been investigated for PLE optimization. A reversed-phase high-performance liquid chromatography (RP-HPLC) coupled to atmospheric pressure chemical ionisation tandem mass spectrometry (APCI-MS-MS) method was developed for the separation, quantification and confirmation. The ion source settings were optimized using a design of experiments (DOE). The optimized method was applied to the determination of these chemicals at very low levels in different samples with a quantification limit of 5 ng/g. Recoveries ranged between 82 and 101% and standard deviations were less than 10%.
