ombined analysis is further developed to encompass
even larger materials science disciplines than previously,
extending it to XRF, Raman and IR spectroscopies. It will first
be used within the frame of the European project SOLSA. The
SOLSA project aims to construct an analytical expert system
for on-line-on-mine real-time mineralogical and geochemical
analyses on sonic drilled cores, an unprecedented challenge
both in terms of instrumental, methodological and software
developments. Two instrumental developments will be carried
out during this European project, one at the laboratory scale
(ID1) deserving methodological testing, the other at the
operational on-mine scale (ID2). At present, only ID1 is achieved
for first tests. This instrument will perform simultaneously x-ray
diffraction experiments, coupled to x-ray fluorescence, Raman
and IR spectroscopies. It consists in a 4 circles diffractometer
equipped with a curved position sensitive detector and a
Cu micro source, a fluorescence detector, and an innovative
system of fiber optics and mirrors to achieve Raman and IR
probing. All the four experiments are able to probe a flat
surface sample within approximately the same sampled
volume. In order to benefit of the complementarity of the four
techniques, an expert system able to refine all datasets has to
be developed. For the x-ray diffraction and fluorescence parts,
the actual combined analysis methodology is operational for
structure, microstructure, texture, stress, phases and element
analyses. Complementing the combined analysis approach by
Raman and IR spectroscopies are targeted in this project to
help phase identifications and quantifications. In this aim the
expert system will use open databases, either already existing
like the crystallography open database, or to be developed
like the Raman open database. We will illustrate the actual
state-of-the-art combined analysis and envision its near-future
developments within the spectroscopy’s context.
