Energy Dispersive Spectrometry,lo electron-volts (keV), and it can produce that spectrum from a micron-sized sample that has had only minimal preparation. Modern software makes interpreting the spectra fairly simple and investigators can obtain a qualitative, or even semiquantitative elemental analysis of their sample in short or

Samples and Spectra,rom a few microns to several inches across, depending on the size of the stage on the SEM. There are, however, two major requirements for the specimens: they must be dry and they must be conductive. Because the SEM operates with a vacuum in the range of 10.–10. Torr, specimens must be dry. This is n

The Spectra,. In cases where the mineral is a member of a solid solution series the spectrum is labeled as being ‘end member rich,’ e.g. Pyrope rich Garnet (page 49) although the end member formula is given. The microscopist can estimate the approximate pyrope percentage based on relative Mg, Ca, and Fe peak he

identify minerals with an Energy Dispersive Spectrometer (EDS). It is also amazing how long it takes someone who is not good at mineralogy to search through a mineralogy text, trying to match the peaks on their unknown spectrum with the chemical formula of some mineral. After the mineral is finally
