Název v původním jazyce

Critical evaluation of a new method for quantitative determination of minerals in solid samples

Popis výsledku v původním jazyce

The new method for the Chemical Quantitative Mineral Analysis (CQMA) is presented and critically evaluated. The percentages of minerals are calculated of the elemental bulk chemical analysis using identified minerals and their crystallochemical formulas. For this calculation an optimization procedure is used. CQMA enables also the feedback calculation of the bulk chemical analysis from CQMA calculated mineral contents. Subsequent comparison of the feedback calculated bulk chemical analysis and actual bulk chemical analysis of the same sample is used for critical evaluation of the input data. If necessary the input data are completed and/or reanalyzed and used for repeated calculation to achieve better match between the feedback calculated and actual chemical analyses, which consequently leads to more accurate mineral analysis. Moreover the feedback bulk chemical analysis can be also separately calculated from any mineral analyses determined e.g. by XRD, FTIR and/or optical method. Six German rock reference samples representing a very wide range of minerals and chemical composition of materials were selected and their mineral analyses carried out by CQMA and Rietveld X-ray diffraction methods. The results were compared with reference mineral analyses and critically evaluated.
