X - RAY SPECTRA of MINERALS and MATERIALS

Each of the x-ray spectra below were obtained using an ARL SEMQ Electron Microprobe operated at 20 kV accelerating voltage, 50nA beam current, 52.5 degree x-ray take off angle, a Kevex 2003 energy dispersive x-ray detector (EDS) biased at 620 volts with an 8 uM thick beryllium window and a PGT MCA 4000 multi-channel analyzer. The resolution of the detector is 159 eV at Mn K alpha.

Energy dispersive x-ray spectra are subject to a number of serious peak overlaps due to the relatively poor x-ray resolution of this technique. Here are some to be aware of:

Mg and As. -- Pb, Mo, S, Tl and Bi -- W, Si and Ta -- Ba and Ti -- all REEs -- Nb and Zr -- Ka vs Kb of V, Mn, Cr, Co, Fe, Ni, Cu and Zn.

Cannon Microprobe's SEMQ is equipped with 6 full scanning wavelength dispersive x-ray spectrometers which resolve these overlapped peaks in the analysis process.

Note that elements with atomic number 10 and smaller are not detected by this system due in part to thickness of the beryllium window on the detector. Therefore, among the elements important in minerals, H, Be, Li, C, N, O and F are not shown in these spectra

The purpose of this database is to provide customers of Cannon Microprobe with reference spectra which can be associated with data from jobs undertaken at this lab.

The horizontal scale on the spectra plots is in keV energy units with 0.0 keV at the left edge and 20.00 keV at the right edge. A few important markers are Si Ka @ 1.739 keV Fe Ka @ 6.398 Cu Ka @ 8.04 keV. The vertical scale is relative count rates or x-ray signal intensity.

The spectra images can be "clicked on" and saved to the user's own file folder.

A "search by element" program such as Materials Data Incorporated's "Mineral" or an online search program such as www.mindat.org or www.webmineral.com will make the search for unknown minerals by elemental constituents easier. Some of the data for theoretical analyses in the following spectra come from Webmineral.

Higher quality hardcopy images of the spectra with scale units are available at a cost of 75 cents each.

The materials used to derive the spectra are available from Cannon Microprobe.
