A new technique, PIXE - Particle Induced X-Ray Emission, for analyzing concentration of trace elements with a detection concentration in parts per million is presented in this paper.

PIXE is performed on a sample by using a proton beam. The experimental results are obtained from a number of coal and ash samples useful for the combined cycle power plants. The technique is useful for deposit analysis and analysis of eroded and corroded surfaces. This technique can identify depth of deposit and chemical constituents simultaneously.
