Tl. Barry et al., PURGE-AND-TRAP GAS-CHROMATOGRAPHIC MASS-SPECTROMETRIC DETERMINATION OF BENZENE IN DENTURE ADHESIVES, Journal of AOAC International, 78(2), 1995, pp. 413-418
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.
