GSC electron microprobe (15 oxides, incl. SO3)



Geological Survey of Canada electron microprobe analysis-Samples are analysed for 15 different major and minor element oxides.

General Methodology:

Mineral analyses of 15 oxides were acquired on a Cameca SX-50 microprobe fitted with 4 wavelength-dispersive spectrometers, with a take-off angle of 40 degrees.  The operating conditions were 20kV accelerating voltage and 10nA current, using a focused beam.  Count times were 10 seconds on peak and 5 seconds off-peak. The ZAF matrix correction program used was that of Armstrong (1988).  Reference standards used were a mixture of natural and synthetic pure metals, simple oxides and simple compounds.
