X'pertPro X-Ray Diffractometer

Structure Determination for Polycrystalline Substances

X'pert Pro Multipurpose X-Ray Diffractometer


Location: Jesser Hall room 108

The X'Pert Pro diffractometer from Malvern-Panalytical performs a variety of X-ray diffraction measurements on any type of polycrystalline material including inorganic, organometallic and organic substances. It can be easily configured by each user with the optimal combination of optics, detector and sample stage for their experiment and is most often used for point-focus experiments and teaching.


XRD Technique Summary:

  • Non-destructive analysis of any polycrystalline material including powders, pressed pellets, fibers, thin films and bulk materials
  • Determine the 3-D structure of any crystal phase at the atomic or molecular level
  • Determine texture, stress and other properties that influence the crystal structure
  • Compare your material to hundreds of thousands of known materials in published databases
  • Make measurements in manual mode or build a program
