Leading Australian supplier of scientific instruments, AXT Pty Ltd has won the bid to supply the Mawson Institute at the University of South Australia with a Rigaku D/Max Rapid II Dual Wavelength Micro X-Ray Diffractometer.
A highly advanced lab-based micro diffractometer, the system offers a number of features and capabilities over and above standard powder diffractometers. In particular, the high intensity MM007 DW Microfocus Rotating Anode of the Rapid II offers class leading resolution with the ability to perform XRD on areas as small as 10µm and carry out spatially resolved analyses and X-Y mapping thanks to the high-precision stage, allowing the detection and identification of minor but crucially present phases, small particles, inclusions or impurities.
The Rigaku-pioneered rotating anode technology works in harmony with the Rapid II 2D Area Image Plate Detector that features no electronic noise or background as well as a wide dynamic range that is equally sensitive to all wavelengths to produce results of the highest quality. Unlike other diffractometers, entire components can be examined, without the need to turn the sample into a powder, making it a form of non-destructive testing. This makes it ideal for examining PCBs, welds and bonds.
Professor Andrea Gerson, one of the key personnel responsible for Mawson Institute choosing the Rapid II diffractometer explained that they were drawn to the Rigaku Rapid II system’s flexibility and versatility. The system will be supplied configured to carry out non-ambient transmission studies, stress and texture analyses as well as general bulk powder measurements.
This facility will be of particular importance to mineral science. Some of the projects already lining up for analytical time on the Rapid II include the examination of secondary mineralisation formation during acid mine drainage, formation of surface layers during copper ore hydrometallurgical processing, analyses for trace value minerals such as uranium containing minerals and for trace toxic minerals such as selenium containing minerals and scale formation during alumina Bayer processing, etc.
The Rapid II will help the Mawson Institute stay at the cutting edge of minerals and materials research and extends existing capabilities including X-ray photoelectron spectroscopy, transmission electron microscopy and confocal microscopy. It will also aid their commercial collaborators by accelerating product development and integration of new technologies into next generation manufacturing.
The Mawson Institute’s purchase of the Rigaku Rapid II system was funded by the University of South Australia, Adelaide University and the ARC Linkage Infrastructure, Equipment and Facilities Scheme.
