The 6th Chinese National Conference on Secondary Ion Mass Spectrometry（SIMS China Ⅵ）,which was hosted by Key Laboratory of Separation and Analysis, Chinese Academy of Sciences, Dalian Institute of Chemical Physics, was successfully held in DICP on October 8th-11th, 2016. Group leader Professor Haiyang Li from Group for Rapid Separation and Detection (102) served as chairman of the conference. More than 110 SIMS scholars from government, research institutes and universities attended the symposium, such as Prof. Ian Gilmore, from Science National Physical Laboratory(NPL), UK, Prof. Andrew Ewing, from University of Gothenburg, Sweden, Prof. David G. Castner, University of Washington, Prof. Jiro Matsuo from Kyoto University, Japan, Prof. Liangzhen Zha from Tsinghua University, Prof. Yongjian Ling from National Tsinghua University, Taiwan, Prof. Dunyi Liu from Institute of geology of Chinese Academy of Geological Sciences, Prof. Xinhua Zhou and Prof. Xianhua Li from Institute of Geology and Geophysics of Chinese Academy of Sciences, Prof. Fuyi Wang from the Chemical Institute of Chinese Academy of Sciences. Top scientists made wonderful conference invited reports, for instance, Prof. Ian Gilmore，the previous chairman of the International SIMS conference, Prof. Jiro Matsuo，the chairman of the next International SIMS conference and Prof. Andrew Ewing，the associate editor of American Analytical Chemistry journal, etc. 
At the conference, experts and professors reported wonderfully for instrument research, theoretical development and application in different fields of SIMS, which triggered a heated discussion of the participants. Group for Rapid Separation and Detection (102) reported the research development of the major instrument special high resolution time-of-flight mass analyzer of "TOF-SIMS Scientific Instrument for Isotope Geology", The resolution of their developed TOF-MS is more than 500,000 (63Cu) which has reached the most advanced level in this research field.
Before the official conference started, in order to popularize the basic theoretical knowledge of SIMS, academic committee and organizing committee invited experts in the field of mass spectrometry and SIMS such as Prof. Huanwen Chen from East China University of Technology, Prof. Zihua Zhu from Pacific Northwest National Laboratory(PNNL), Prof. Wei Yang from Institute of Geology and Geophysics of Chinese Academy of Sciences, Prof. Haiyang Li from Dalian Institute of Chemical Physics of Chinese Academy of Sciences to give a one-day training course about the basic knowledge of SIMS, instrument and its analytical application for graduate students and young researchers.
After the conference, all guests visited the laboratory for Rapid Separation and Detection (RSD) and the science park of DICP under the guidance of Prof. Li. In the laboratories, the guests investigated in detail for the operation of high resolution mass analyzer of the TOF-SIMS which was dedicated to high precision isotope abundance research. The experts and scholars had a live communication around the field application of photo ionization TOF-MS, which was self-developed by the 102 laboratory, on the environmental analysis, life analysis and the scientific research of ion mobility spectrometry（IMS）on the field of medical diagnosis, rapid detection of explosive, etc. Meanwhile, they gave Group 102 high praise for their self-developed and industrialized rapid analytical instrument towards national security, ecological environment and life health.
The conference offered a platform for the academic study, technical communication and cooperation and exhibited updated research results for the field of Chinese SIMS. We hope the conference will promote the development of Chinese SIMS. (Text by Chenxin Wu, Mei Li, Image by Ping Chen, Qingyun Li）
