Quantitative PIXE analysis of single fly ash particles by a proton microbeam

Methods of quantitative PIXE analysis of individual particles in the diameter range between 5 and 10 mum are presented. Two different approaches to the analysis are considered. In the first case, an analysis is performed with a proton microbeam centered at the middle of the particle. In the second case, the beam is scanned over the whole particle. Absorption correction methods were developed for both cases. Advantages and drawbacks are discussed on the basis of analysis of individual fly ash particles.
