Empyrean

The intelligent diffractometer

With the 3rd generation Empyrean, Malvern Panalytical has now redefined the concept of a multipurpose diffractometer: our newly designed MultiCore Optics enable the largest variety of measurements without any manual intervention. Empyrean has the unique ability to measure all sample types – from powders to thin films, from nanomaterials to solid objects – on a single instrument. The world of materials science is constantly changing and the life of a high performance diffractometer is much longer than the typical horizon of any research project. With Empyrean, you are ready for anything the future holds.
