Abstract

Individual particle analysis by means of an automated scanning electron microscope with an energy dispersive X-ray microanalysis system (SEM/EDX) is used for chemical classification and size determination of airborne particulate matter. Special attention is paid to the X-ray analysis of atmospheric soot particles. The preparation and use of standards, which is indispensable for obtaining good results are described and discussed in detail. The aerosol samples were collected on Nuclepore filters of two different pore sizes at a traffic island in Munich.
