Headspace solid-phase microextraction and on-fibre derivatization of primary aromatic amines for their determination by pyrolysis to aryl isothiocyanates and gas chromatography-mass spectrometry

A sensitive and solvent-free procedure for the determination of aromatic amines in environmental and food samples was studied using solid-phase microextraction (SPME) for on-fibre derivatization and gas chromatography-mass spectrometry (GC-MS). The analytical procedure involved headspace impregnation of allyl isothiocyanate on the SPME fibre and then extraction/derivatization of aromatic amines by placing impregnated fibre in the headspace of...
