Abstract

Geoscience research using the proton microprobe demands an accurate analysis method for all element concentrations, particularly those at low levels where the proton probe is providing unique trace element data. A method, and its integration into the GEO-PIXE suite of computer codes, is described which meets these requirements, with particular emphasis on elements near the detection limit. Results using the method are compared with accepted analyses of standard rocks and electron microprobe analyses. Monte Carlo tests indicate that the method is accurate for low level trace elements near the detection limit, and for demonstrably different spectra for which standards comparisons cannot be readily made.
