RESUMEN

The chemical components of mainstream smoke were trapped by the artifical salvia. A novel method) for the analysis of the trapped chemical components was established using stir bar sorptive extraction(SBSE)) followed by a thermal desorption-gas chromatography-mass spectrometry(TD-GC-MS). The major) factors including desorption temperature, desorption time, cryofocusing temperature, extraction time and the addition of sodium chloride were studied. Under the optimized conditions, the average relative standard deviation(RSD) of peak areas of 44 components which were identified from the artifical saliva for 6 determinations was less than 10%, which showed the good repeatability of this method. The experiment result indicated that the SBSE-TD-GC-MS technique provided a powerful tool for the analysis of smoke components of some cigarette) trapped and dissolved in the saliva.
