In quantitative x-ray diffraction (XRD) analysis, the reference intensity ratio (ki or RIR) is one of the most important parameters of the reference intensity method (RIM). The ki is a function of the intensity of x-ray reflection and the mass attenu

Speciation results from earlier methods of quantitative analysis of TSP, dichotomous, and PM 10 filters for compounds by XRD were often marginal to unacceptable because of very light loadings and the interfering effects of substrate fibres in cases o

Pure phase reference intensity ratio determinations were completed on eleven biotites ranging in Fe composition from χFe = 0.058 to χFe = 0.695, where χFe = Fe/(Fe + Mg). The crystal chemistry of biotites requires that the intensity of diffraction

Reference intensity ratios (RIR or ki) may be used with powder diffraction intensities obtained from convergent-beam transmission scattering once the intensities have been corrected for irradiated volume variations that are a function of the angle (t

Two methods may be used to measure the reference intensity ratio: (1) by measuring intensities from samples prepared by mixing the analyte and standard together in a known weight ratio and (2) measuring separately the intensities for the analyte peak
