D2 PHASER is a portable desktop XRD instrument for research and quality control. The system delivers high quality measurement data, which allows performing advanced analytical methods, such as the standardless quantitative Rietveld phase analysis. This report demonstrates its use for the determination of the different sulphate phases in natural Gypsum or Anhydrite.

X-ray powder diffraction combined with TOPAS Rietveld analysis is nowadays one of the most powerful methods existing, to perform quantitative phase analysis. In the last years it became a standard tool in research and development, but also in the minerals and mining industries.
