Inter-element correlation graphs from two-dimensional scanning X-ray fluore
scence micro-beam spectrometry measurements of individual particles were mo
deled in the previous theoretical part of this study. It was shown that the
investigation of the correlation graph gives an opportunity to find a simp
le geometrical shape to model individual particles. In the present work ind
ividual oil and coal fly ash particles were studied as an application of th
e method. The absorption characteristics of the residual matrices of the pa
rticles could be estimated from the width of the correlation plots. Inter-e
lement concentration ratios were estimated from the slopes of the respectiv
e correlation graphs. These data were compared with the values determined b
y measuring a thin glass calibration standard NIST 1832. (C) 2000 Elsevier
