| Research Abstract |
A microbeam system has been developed for the analysis of single aerosol particles. Combination of PIXE, RBS and off-axis STIM methods enabled simultaneous analysis for hydrogen to metal elements. Aerosol particles were collected on thin polycarbonate film (〜0.3 μm) resulting in good signal-to-noise ratio. Quantitative elemental correlation was measured for single aerosol particles. A total of 270 particles were analyzed and clustered into 4 groups.
By combining PIXE with RBS, off-axis STIM and direct STIM methods and by using thin backing film, we can quantify single aerosol particles containing elements from hydrogen to heavy metals, thus revealing the chemical composition of these particles.
The chemical composition provides information on source identification and leads to better understanding of the aerosol formation mechanism. The described micro-beam analysis system represents a powerful research tool for aerosol particles, emission source identification and for a better understanding of the aerosol formation processes.
