Paper Abstract

The 'on line' and 'in situ' detection of polycyclic aromatic hydrocarbons (PAHs) in exhaust aerosols of combustion processes is still one of the important tasks in analytical chemistry. Accordingly, within the framework of a scientific project with the financial support of the German Minister for Education, Science, Research and Technology, STN ATLAS Elecktonik GmbH, Bremen, is developing a fully automatic sensor system for the detection of PAHs absorbed on particles in exhaust aerosols. Time-resolved spectra of laser-induced fluorescence are measured. Two parameters, the decay time and the wavelength of the fluorescence are recorded and evaluated for the classification of different PAHs. In this paper the sensor system is described in detail and results of measurements in the exhaust gases of various industrial plants are shown.
