The new product expert appraisal meeting of "SP-3800 Series High Performance Self-absorption Background Correction Atomic Absorption Spectrometer" developed by Shanghai Instrument Instrument Co., Ltd. organized by China Instrumentation Society and China Analysis and Testing Association was held at the headquarters of Shanghai Spectrum Company. Experts attending the appraisal meeting were Academician Zhuang Songlin of Shanghai University of Technology, Professor Zhu Liangyi, Honorary Chairman of Chinese Society of Analytical Instruments, Researcher Yan Chengde, Vice Chairman of Chinese Society of Analytical Instruments, Researcher Jiang Shiqiang of Chinese Academy of Agricultural Sciences, Professor Qiu Deren of Fudan University, Professor Qiu Deren, Fudan University Researcher Wang Zhihong of Institute of Technology, Researcher Yang Xiaotao of China Geological Experiment Center, etc. Academician Zhuang Songlin presided over this new product appraisal meeting. At the meeting, Liu Yaohan Senior Engineer and Liu Zhigao Engineer of Shanghai Spectral Instruments Co., Ltd. introduced the development of the project and the main achievements of the research and development to the experts. In 1978, Liu Yaohan Senior Engineer proposed the self-absorption background correction method for the first time in the world, and after 29 years, Liu Yaohan Senior Engineer cooperated with Shanghai Spectroscopy Corporation to push this quiet technology for many years to a brand new the height of. The self-absorption background correction technology has low cost and is suitable for China's national conditions, but due to some defects in the technology itself, it has not been well promoted and applied for a long time. In response to this situation, the project team has conducted a lot of basic research under the leadership of Liu Yaohan Senior Engineer, and has achieved fruitful results. Through technological innovation and through a large number of experiments, they figured out a set of information processing, optical noise reduction, gap control lamp, "mercury lamp-reagent" gradient measurement and other original or first-of-its-kind proprietary technologies (inventive patents have been applied) to make deuterium lamps The dual-background correction technology of the self-absorption effect of the element lamp achieves and exceeds the performance level of similar international products; it is comparable to the Zeeman background correction in the ability of element analysis that most people care about at present. Based on the above research results, Shanghai Spectroscopy Company successfully developed the SP-3800 series of high-performance self-absorption background correction atomic absorption spectrometer with international advanced level. At the appraisal meeting, the experts of the appraisal committee carefully listened to the development report, test report, new report, expert evaluation report and user use report made by the project completion unit, and reviewed the relevant technical information, visited the instrument and on-site demonstration, passed Questions, answers and serious discussions, experts agreed that the core technology of self-absorption background correction researched by the project has completely independent intellectual property rights. The developed instruments are in the leading position in the country and have reached the international advanced level. Therefore, it is recommended to promote the use as soon as possible and include them in national independent innovation products.
