Abstract
The gas phase components in the mainstream cigarette smoke were investigated by tunable synchrotron vacuum ultraviolet (VUV)/photoionization mass spectrometry (PIMS). First, the smoke was collected by a modified glass syringe. Photoionization mass spectra for the smoke were obtained directly on-line, without pretreatment and separation. Second, ionization energies (IE) of the components at each mass-to-charge ratio (m/z) were obtained by scanning the photoionization efficiency (PIE) spectra. The possible components could be assigned by comparing the experimental IE with known NIST database. Final, the puff-by-puff resolved behaviors of some components were studied by using a modified commercial smoking machine combined with PIMS.
