摘要：

Plasma-based SNMS has been employed to perform a depth-resolved elemental analysis of aerosol particles collected in a suburban area near Karlsruhe. Two classes of particles could be distinguished. Both of them exhibited a significant depth structure. Submicron particles have been found with a 15 nm deep ammonium sulphate surface layer on carbon rich cores. The other class consisted of coarse particles of several mu m size which even showed a double layer system enclosing geogenic cores. For depth-scaling a new internal calibration procedure has been tested and found to be suitable for the complex environmental material. Dynamic SIMS measurements have been used to investigate especially the carbon compounds of the particles by evaluation of small cluster ion signal patterns.
