Analysis and Test Center

Analysis and Testing Center was established in 1991. It is equipped with sophisticated and analytical instruments to provide teaching and research services for the University. There are currently field-emission transmission electron microscopy analysis and test platforms and environmental scanning electron microscope(with energy dispersive spectroscopy and other accessories), X-ray diffraction (XRD), Fourier transform infrared spectroscopy, thermal analysis, optical microscopy and image processing systems and several imported analytical instruments. In addition, dozens of other related sample preparation and analysis equipment is accessible, which is an advanced and interdisciplinary test platform integrated to collect sample preparation, detection and analysis. Its area takes up about 900 square meters, and fixed assets is about RMB 30 million. The current staff have senior professional and technical positions，including 1 professor, 3 associate professors , 4 senior engineers, a New Century Talent of Ministry of Education, an excellent expert with outstanding contribution in Sichuan Province and an academic and technical candidate of Sichuan Province, involved in machinery, materials, biomedical engineering, geology, physics, chemistry, precision instruments and testing technology, electronics and other disciplines, engaged in analysis and testing for many years. Analysis and Testing Center can be widely used in the field of teaching and research of metal, semiconductor materials, polymers, ceramics, nano-materials, chemicals, environment, biology, geology, physics.It provides high-quality technical consulting and services for the majority of students and enterprises.
