Oy. Belozerova et al., Particle size account in electron probe X-ray microanalysis of solid sediments in snow cover, J ANALYT CH, 54(1), 1999, pp. 24-27
A procedure for particle size account in electron probe X-ray microanalysis
of solid sediments (fine fractions, 1-5 mu m) in snow cover is proposed. T
he correction factors and the concentrations of test elements are determine
d within a modified biexponential model of the distribution of characterist
ic X-ray radiation over the depth of a sample with joint corrections fur ab
sorption and atomic number. The validity of the correction for particle siz
e is evaluated by comparing the experimental data on the fine fractions and
coarse grains of minerals with known compositions; The described procedure
for particle size account makes it possible to substantially decrease the
error of elemental analysis in electron probe X-ray microanalysis for sampl
es with particles 1-3-mu m in size.
