Purge-and-Trap Gas Chromatographic-Mass Spectrometric Determination of Benzene in Denture Adhesives.
A purge-and-trap gas chromatographic-mass spectrometric procedure is presented for determination of trace levels of benzene in denture adhesives and their raw materials. The limit of quantitation is 10 ppb, reproducibility is +/- 10%, and recoveries of d6-benzene are 70-85%. Results of a nationwide survey of 109 finished products and their raw materials representing 32 brand name products from 17 manufacturers are reported.
