Discrimination criteria are proposed for selecting irregularly shaped and unpolished fine grains for quantitative analyses by energy dipersive X-ray (EDS) spectroscopy. The basic principle is that the energy distribution of the continuum or background radiation is a direct indication of the orientation of the particle surface at the point of analysis. Background spectra were collected from pure elements in various geometric configurations and orientations from which it was observed that the low-energy (<4keV) portion of the spectra was most sensitive to the orientation of the specimen surface, showing a strong increase in intensity with increasing specimen tilt up to about 40°
