AXT Pty Ltd will supply a TESCAN Integrated Minerals Analyser (TIMA) to Curtin University in Western Australia.

The John de Laeter Centre (JDLC) at Curtin University in Western Australia recently placed an order for an automated minerals analyser based on scanning electron microscope (SEM) technology after a competitive selection process. This is the second TESCAN electron microscope to be purchased for the JDLC. AXT had commissioned a TESCAN MIRA Schottky Field Emission Gun (FEG-SEM) instrument for large area Energy Dispersive Spectroscopy (EDS) and Electron Backscatter Diffraction (EBSD) mapping of minerals in January 2014.

Available in a choice of two platforms, Curtin University has selected the more powerful (FEG-SEM) platform based on the MIRA design.

Key features of the Curtin TIMA system include larger GM fully analytical chamber allowing loading of up to 15 x 30mm diameter samples and as many as 20 detectors and accessories; seamless integration of EDS detectors and software to rapidly and automatically analyse samples for mineralogy using three measurement modes - modal analysis, liberation analysis and bright phase search; and TESCAN’s unique compact Rainbow cathodoluminescence (CL) detector ideally suited to the identification of different mineral phases, allowing simultaneous CL and Backscatter (BSE) imaging.

According to Prof. Brent McInnes, Director of the John de Laeter Centre, the TIMA acquisition is jointly funded by a research consortium including Curtin University, the University of Western Australia, Murdoch University, the Geological Survey of Western Australia, the Australian Research Council and the WA Office of Science. JDLC looks forward to working with AXT and TESCAN to build a Digital Mineralogy Hub in Western Australia for minerals, energy, materials and environmental research.

He added that the TIMA will play a critical role in managing the micro-analytical workflow of several JDLC facilities including over $20M of ion, laser, electron and atom microprobe instrumentation.

The TIMA installation is scheduled for November this year. AXT and TESCAN will continue to provide ongoing hardware and software support and maintenance for their systems.
