EMPYREAN ALPHA-1Unrivalled data quality from a laboratory XRD system

PreFIX: TRUE FLEXIBILITY FOR ALL OF YOUR CRYSTALLOGRAPHIC NEEDSThe key to the Alpha-1’s flexibility is its ingenious use of Malvern Panalytical’s PreFIX (Pre-aligned Fast Interchangeable X-ray) technology. This kinematic mounting system is applied to optics, stages and even the tube housing, and allows the diffractometer to be reconfigured in minutes without realignment.

In five minutes or less, the high-resolution Alpha-1 diffractometer becomes a multipurpose diffraction system ready to tackle a variety of analytical challenges.

ENGINEERED TO BE THE BEST The Empyrean Alpha-1 is a member of Malvern Panalytical’s family of Empyrean X-ray diffraction systems. In the Alpha-1, a unique symmetric Johansson monochromator provides data with unrivalled resolution, excellent peak symmetry, and ultra-low background - perfect for structural analysis needs.

Superior Johansson monochromator design

Whereas some Johansson monochromators use an asymmetrically cut crystal, Malvern Panalytical employs a symmetrically cut, curved Ge (111) crystal to deliver superior resolution and spectral purity.

The Kα1 X-ray beam is concentrated on the virtual line focus position of the Bragg-Brentano geometry.

Malvern Panalytical’s unique monochromator positioning motor allows easy fine-tuning of the monochromator alignment without the need for outdated practices which compromise the safety of the system.

Copper or cobalt X-rays – your choice

The Alpha-1 system can be set up with either a copper (Cu) or a cobalt (Co) X-ray tube, depending on the type of materials analyzed most frequently. For iron and cobalt bearing materials, the use of Co radiation instead of Cu results in higher peak intensities and therefore a much improved peak-to-background ratio when analyzing these materials.

Conclusion:The Empyrean Alpha-1 is ideal for: • solving structures from powder data• searching for polymorphic phases where peak overlap is a hinderance•  studying nanomaterial peak profiles to extract crystallite size, dislocation densities, and residual

stress• preparing materials for synchrotron beam time
