Energy Dispersive X-Ray Spectroscopy for the Determination of Trace and Main Elements

Abstract
The results from various sarnples reported here show that energy dispersive x-ray spectroscopy is available as an efficient analytical method; one that has emerged from the qualitative and semi-quantitative overview analysis phase. Particularly the ability to improve sensitivity or reduce statistical error using optimized excitation has led to an important advancement in capturing the primary signal. The simultaneous measurement of a wide range of elements enables utilization of all of the information contained in a spectra for the evaluation; allowing for new approaches for the evaluation of spectra, particularly for the consideration of matrix influences.
