Abstract
A purge-and-trap gas chromatographic-mass spectrometric procedure is p resented for determination of trace levels of benzene in denture adhes ives and their raw materials. The limit of quantitation is 10 ppb, rep roducibility is +/- 10%, and recoveries of d(6)-benzene are 70-85%. Re sults of a nationwide survey of 109 finished products and their raw ma terials representing 32 brand name products from 17 manufacturers are reported.
