The photoelectric aerosol sensor (pas) as a fast-responding detection system for pahs in cigarette smoke

The combination of the photoelectric aerosol sensor (PAS) and a time-programmed sampling of small aerosol volumes within a puff allows the quantitative time-resolved determination of photoemitting substances in the aerosol. All photoemitting substances contribute to the measured photoelectric (PE) signal. In this study it is shown that the PAS signal correlates with the amount of nine polycyclic aromatic hydrocarbons (PAHs) in mainstream cigarette smoke. The PAHs were separated by HPLC and detected by fluorimetry.
