Among the refined parameters are scale factors for each phase, from which the quantitative analysis is derived.

In a Rietveld refinement, we use the crystal structures of all of the phases and diffraction physics to do a least-squares modeling of the full diffraction pattern. While these traditional single-peak or peak-cluster techniques can be used if necessary, Poly Crystallography generally determines quantitative phase analyses by the Rietveld method.

The traditional techniques for quantitative phase analysis are described in standard textbooks, such as: Thus, the concentrations of phases in a mixture can be determined by measuring the intensities of peaks in the powder pattern. Quantitative Phase AnalysisĪs the concentration of a phase in a mixture varies, the intensities of all of the peaks from this phase vary in concert (ideally).

To learn more about how to identify trace phases, come to the workshop on Trace Phase Identification Using Chemical Information at the 2010 Denver X-ray Conference (taught by Tim Fawcett and Jim Kaduk. New compounds not present in the database, are (of course) tougher to identify, but such compounds present interesting research problems! Identifying minor or trace phases can require special techniques.
