| Abstract (English): |
To achieve online puff-by-puff analysis on particulate matter in mainstream cigarette smoke, a split-flow injection method that could adjust the smoke sampling volume was developed to minimize smoke cross-contamination between different puffs. Furthermore, an online detection device was established to detect the puff-by-puff release of mainstream cig are tte smoke by combining the split-flow method with the extractive electrospray ionization mass spectrometry (EESI-MS). The experimental parameters were optimized and the stability of the device was evaluated. The trends of puff-by-puff release of different mainstream smoke components were analyzed, and some of these components were compared across cigarettes of different circumferences. The results showed that: 1) Under the optimized experimental parameters for targeted analytes, sharp peaks and stable baseline in total ion chromatograms (TIC) were achieved, and the device exhibited good stability with RSD less than 3%. 2) Within 100-600 mass to charge ratio (mh) range, abundant peaks were observed in the mainstream smoke, and the puff-by-puff releases of components corresponding to different mh mainly showed in three types as follow: first increase and then decrease, first increase and then tending to be stable, or first increase and then continuous increase. 3) For those components corresponding to the same mJz. the puff-by-puff release profiles of the slim cigarette were similar to those of the conventional king-sized cigarette, but the puff-by-puff release of slim cigarettes were more stable.
