Engineered to be the best
The Empyrean Alpha-1 is a member of 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.

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
