The Malvern Panalytical X'pert Alpha diffractometer was installed in the department in 2003. It originally had a high resolution configuration similar to that of the Empyrean alpha 1, but has the high resolution monochromator has since become unusable and the instrument is now used in high-intensity Alpha 1,2 configuration similar to that of the Bruker Advance Eco. The settings on the instrument are not to be changed, making it a reliable choice for high resolution measurements and producing comparable data.
