The electron microprobe is widely applied in the chemical characterization of solid materials, including minerals, metals, and biological specimens. This instrument is used to image and chemically characterize features as small as one micron, and is particularly well suited for quick, accurate, and sensitive analysis of all chemical elements from beryllium (atomic number 4) to the man-made elements beyond uranium (at. no. 92). These elements can usually be detected in concentrations as low as one hundred parts per million or less at the scale of a few microns.
