摘要

In this work the feasibility of Raman spectroscopy, especially the detection limit of this technique for the chemical characterization of multicomponent aerosols, which appear in technical processes has been investigated. In such kind of aerosols high number concentrations (>106 cm−3) can be observed whereas the range of the pollutant loading varies from 10-1000 mg/m3. For these purposes different type of aerosols have been investigated. Aerosols in which the pollutant can be found in the dispersed phase as well as in the gas phase (aqueous solutions of NH3 aerosols), those where the pollutant appears only in the dispersed phase (aqueous solutions containing SO4 2−/ NO3 − salts) and aerosols where there is no Raman shift between the signals of the gas and the dispersed phase (toluene/ dodecane aerosols). Furthermore aerosols generated by the reaction between NH3 and HCl in nitrogen containing different amounts of vapor are also investigated.
