Artificial and atmospheric aerosol particles consisting of light elements were analyzed by grazing‐exit electron probe x‐ray microanalysis with an ultra‐thin window energy‐dispersive x‐ray detector. It is shown that it is possible to observe the surface layer of the particle without any influence of the x‐rays emitted from the core of the particle. Such an approach helps to solve the problem of overlapping x‐ray lines originating from the surface and core of the particle and from the substrate. However, the present experimental setup was only suitable for performing qualitative localized analysis of a single particle. Copyright © 2003 John Wiley & Sons, Ltd.
