The conference was presided over by Tang Weixue, director of Guangdong Industrial Analysis and Testing Center. Ma Shiguang, executive vice president of China Non-ferrous Metal Industry Technology Innovation Strategic Alliance, Liu Min, vice president of Guangdong Academy of Sciences, and Bao Lei, director of National Steel Product Quality Supervision and Inspection Center, delivered speeches respectively.

Then guests respectively on , , and< the LME brand registration process introduce competition to the Ministry of Education of chemical disciplines for the promotion of high quality inspection testing personnel training>, made the subject of the related report entitled.

The next day, according to the types of materials, there were three different sessions to report and discuss: non-ferrous iron and steel energy raw materials and rare metal material product quality analysis and testing. Among them, Zhou Xilin of Chongqing Metrology and Quality Inspection Research Institute made a report on . In this report, the application of UHPS ultra-high pressure system was introduced, which expanded the application range of spark direct reading spectrometer, attracted the attention of the teachers attending the meeting. During the tea break of the meeting, some teachers  came to the booth of Ruishenbao directly to get a detailed understanding of the UHPS ultra-high pressure system of Ruishenbao.

Ruishenbao analysis technology (Shanghai) co.,LTD research and development production of UHPS ultra-high pressure system is provided by hydraulic equipment pressure (maximum working pressure of 3200 kn), low pressure and the pressure relief device control specific pressure, can form a complete set of special used long-term durability under high pressure of special mould, sample program automatic pressure control process, complete ultrahigh pressure automatic sample preparation of a complete set of equipment. Compared with the original conventional manual or electric sample making prototype (the sample making pressure range provided is between 200-600kN), On the one hand, it improves the sensitivity of analytical elements; on the other hand, it can't or is difficult to be directly pressed under conventional pressure, such as ore alloy biological samples, and binder is needed to be added to achieve the direct pressed sample preparation, so as to ensure the surface smoothness, level specification and repeatability of the sample prepared. More UHPS ultra-high pressure system samples preparation spark direct reading spectrometry can focus on Ruishenbao official account, to view the article .
