Abstract
To provide quasi-on-line information on the elemental chemical composition of heavy metal aerosols, laser-induced plasma spectroscopy (LIPS) is employed. The major objective of this work is to develop a transportable and low cost sensor system for an on-site analysis of aerosol filter samples. The presented system is based on a laser unit and a detector unit including the spectrometer with a 0.275 m Czerny-Turner- spectrometer and a gateable intensified CCD-camera. Both unites are connected to a miniaturized sensor head via fiberoptics. A laser plasma is created by focusing the light transmitted through the fiber directly on the surface of a glass fiber filter. Preliminary investigations background limitations due to blank filters and heavy metal aerosol loaded filters are given.
