A new technique, PIXE - particle induced x-ray emission scanning, for analyzing concentrations of sodium through uranium with detection limits in the order of ppb and ppm is explained in this paper. The accuracy of scan is 1 ..mu..m and the target can be moved over a distance of 8 inches in any direction for surface or depth analysis. PIXE is performed by scanning the target, in increments ranging from 1 to 8 mm adjustable diameter of proton beam, line by line, using a computer controlled Deadal motor driven linear translation stage in the needed directions. The experimental results obtained from a number of coal and ash samples, using PIXE technique are presented. The degree of accuracy of the PIXE technique relative to other techniques is also discussed. The technique is very useful for coal and ash analyses, deposit analysis, and analyses of corroded and eroded surfaces using coal and coal derived fuels. PIXE is a unique technique which provides quantitative data on concentration of inorganic constituents, its oxidation state and depth simultaneously. Total analysis time in this technique, including sample preparation, varies from 8-10 minutes per sample.
