Abstract:The public analysis and testing center of the material platform in South China University of Technology has been developed for more than 10 years. A set of relatively complete management methods of the open-sharing for large analytical instruments were formed. The specific practice and the results achieved were described. The management mechanism and characteristics were summarized in the aspects of the user training system, the appointment system and the safety management of instruments and labs, which can put forward some suggestions for the construction of the open-sharing for large analytical instruments in universities. The goal of the maintenance of the large instruments absolutely by the test fee has been fully achieved. It's encouraging that the SU8220 cold field emission scanning electron microscope was purchased by using the balance of the test fee. It would promote the sustainable development of our open-sharing platform in the near future.
