Quantitative Phase Analysis Using the Rietveld Method - Estimates of Possible Problems Based on Two Interlaboratory Comparisons
On the basis of data gathered in connection with a certification project, problems were investigated that impair the accuracy of quantitative phase analyses (QPA) using the Rietveld method. Some mechanisms were elucidated by which insufficient counting statistics of the diffraction data or inappropriate data handling and refinement strategy influence the QPA results.
