The first "China Chromatography Manufacturers and Users Dialogue" hosted by the Instrument Information Network was successfully held on September 23 at the Institute of Mechanical Science (Beijing). The news of the Chinese chromatographic community will be uploaded. The first domestically produced GC128 (B-type) automatic gas chromatograph with electronic program pressure flow control (EPC) system was born in Shanghai Precision Scientific Instrument Co., Ltd., and it was in 2005. In August, it passed the acceptance of the Shanghai Science and Technology Commission expert group.
According to Mr. Li Wei, Director of the Analytical Instrument Research Office of Shanghai Precision Scientific Instrument Co., Ltd., this type of instrument is a scientific and technological project initiated by the Shanghai Municipal Science and Technology Commission. It is a collaborative effort between Fudan University and Shanghai Precision Scientific Instrument Co., Ltd. After five years of hard work. Overcoming all kinds of difficulties and finally succeeding. This type of instrument has a number of independent innovation technologies in China. It is a domestically produced high-grade gas chromatography instrument with China's independent intellectual property rights, filling domestic gaps and some technical indicators close to the international advanced level. The instrument realizes the whole process from the introduction of the sample to the analysis report by the microcomputer control management and unmanned operation, with electronic program pressure flow control (EPC); micro thermal conductivity cell body and low noise high magnification amplification circuit system; embedded microcomputer and more CPU system, connected to the Internet, to achieve remote communication, remote diagnosis and remote training.
As we all know, with the increasing automation of gas chromatographs, EPC technology has been installed as a basic configuration on gas chromatographs of many foreign manufacturers, thus providing more reliable and better support for the reproduction, optimization and automation of chromatographic conditions. Domestic gas chromatography instruments have long been in a blank state in this field. The birth of GC128 (type B) marks that the development and manufacturing level of China's gas chromatograph has reached a new height, and it also means that domestic gas chromatographs have begun to challenge foreign manufacturers in high-end fields.
From Mr. Li Wei, the author also learned that Fudan University and Shanghai Precision Scientific Instrument Co., Ltd. have established the “Shanghai Jingke-Fudan Analytical Instrument R&D Laboratory†to give full play to the basic research and commercial design of universities. Their respective advantages. At the same time, drawing on the advanced experience of foreign companies, Shanghai Precision Scientific Instrument Co., Ltd. has formulated a strategy of equal emphasis on product development and technology development in research and development. On the one hand, through the recombination of mature technologies, we can quickly develop targeted new products that meet the needs of different markets. At the same time, we will never relax the independent innovation of technology, so as to reserve technical reserves for the development of the new generation of instruments.
At present, Fudan University and Shanghai Precision Scientific Instrument Co., Ltd. have targeted the next target in the field of organic mass spectrometry, which is now completely monopolized by imported products. The two sides are jointly tackling GC-TOF technology. Mr. Li Xiaoou from the East and West Electronics also said that East and West Electronics is also developing a quadrupole GC/MS, with a view to breaking the situation in the organic mass spectrometry market in China, where foreigners dominate the world.
Cone Crusher
The structure of the cone crusher is mainly composed of a machine frame, a
horizontal shaft, a moving cone, a balance wheel, an eccentric sleeve, an upper
crushing wall, a lower crushing wall, a dynamic coupling, a lubrication system,
a hydraulic system, Control system composed of several parts.
Cone crusher is widely used in mining industry, metallurgical industry,
construction industry, road construction industry, chemical industry and
silicate industry, suitable for crushing hard and medium hard ore and rock such
as iron ore, limestone, copper ore, Quartz, granite, sandstone and so on.
Cone crusher classification
1. Spring cone crusher. Spring cone crusher can be divided into: coarse
crushing spring cone crusher, crushing spring cone crusher and crushing spring
cone crusher.
2. Hydraulic cone crusher.
3.HP hydraulic cone crusher.
4.SMG cone crusher.
Compound cone crusher.
Advantage
1, reasonable structure, broken principle and advanced technical
parameters, reliable operation, low operating costs.
