X’Pert Pro X-ray Diffractometer

The X’Pert XRD is a user-friendly diffractometer, and has features fast data collection with a reasonable background. This is possible because of the combination of the X’Celerator detector and Ni filter. For room temperature XRD patterns, there is no height alignment, a parameter file is loaded, and the XRD pattern is recorded. Training and subsequent usage are straightforward. The 1600°C furnace with a platinum heating strip allows in situ XRD to be undertaken in air, vacuum, or flowing inert gases. The spinner stage and flat stages allow a variety of sample shapes and forms to be measured. The transmission spinner can allow enhanced measurements of organic compounds and samples with texture issues.
