[China Instrument Network Instrument R&D] On September 26, the Condition Protection and Finance Bureau of the Chinese Academy of Sciences organized the 2012 Academy of Equipment Development Project Acceptance Meeting to conduct the “Elemental Component Non-contact Rapid Analyzer†project led by Shenyang Institute of Automation, Chinese Academy of Sciences. Acceptance. The relevant personnel of Shenyang Automation Institute Science and Technology Department, Finance Department, Industrial Control Network and System Research Office attended the acceptance meeting.
Acceptance expert conducts on-site acceptance test
The expert group heard the project work report of the project leader Sun Lanxiang and asked questions; reviewed the relevant documents, and conducted on-site technical tests on the instrument and equipment to form technical test opinions. After careful discussion, the expert group affirmed the completion of the project and agreed that the project passed technical acceptance. At the same time, financial experts reviewed the financial status of the project.
The "Elemental Component Non-contact Rapid Analyzer" project overcomes key technologies such as laser plasma long-distance excitation, long-range efficient collection of plasma emission, low signal-to-noise ratio, and feature extraction of weak spectral signals, achieving the requirements of the implementation plan. Assessment goals and technical indicators. The developed instrument uses double-pulse laser-induced plasma technology to enhance the plasma signal, and combines the Cassegrain telescope structure to efficiently collect long-distance signals, breaking through the difficulties of long-distance excitation and detection, and adopting wavelet filtering to change the threshold and change the decomposition layer. The number method improves the signal-to-noise ratio, uses an optimized curve fitting method to separate overlapping peaks, and uses range feedback to correct the calibration model, improving the quantitative measurement accuracy. Instruments and equipments were used in demonstration applications at the Institute of Metals of the Chinese Academy of Sciences and Fushun New Steel Co., Ltd. to meet the on-site use requirements and gain user approval.
Relevant research results have been applied in many applications such as iron and steel smelting, aluminum alloys, electrolytic aluminum, and copper smelting. No cumbersome sampling, sample delivery, and sample preparation processes are required. Online real-time monitoring of chemical components can be realized, and products can be greatly improved. Quality and production efficiency have achieved good operational results. The product will open a new online analytical instrument market at home and abroad, with a very wide range of application prospects.
