PROBLEM TO BE SOLVED: To provide a method and apparatus for identifying a material by using a sample-specific reference spectral list or library.SOLUTION: A sequential approach to SEM-EDS automated mineralogical classification is carried out by performing two or more material classification analyses. A pre-classification step restricts processing of spectra deconvolution algorithms to a subset of spectra that pass a dominant mineral criteria, resulting in a significantly reduced subset of reference spectra that occur within a measured sample in pure enough form at a given minimum quantity. The following complex classification stages involving deconvolution of multiple constituents within measured spectra is based on this sample-relevant subset.SELECTED DRAWING: Figure 7 |
