Wavelength Dispersive Spectroscopy?
The main function of the electron microprobe is to produce highly accurate and precise quantitative chemical analyses of areas as small as 1-2 microns (1-2 thousandths of a millimeter) in diameter using wavelength dispersive spectrometry (WDS). Our microprobe is optimized to analyse elements in the range of Boron (Z=5) through Uranium (Z=92). Our probe can also analyze Beryllium (Z=4) under optimal conditions. Detection limits for common elements using WDS are in the range of 100-500 ppm, although the instrument can be set up to detect and analyze elements with concentrations in the single ppm range (given very long count times). Our new SAMx automation system allows us to obtain about 25-30 15 element analyses per hour once standardization is completed.
