Beijing Jinsuokun Technology Development Co., Ltd.
Beijing Jinsuokun Technology Development Co., Ltd. (formerly Xi'an Sokun Technology Development Co., Ltd., which is controlled by the State General Nonferrous Geological Administration and jointly owned by the Northwest Geological Exploration Bureau and the Northwest Nonferrous Geological Research Institute) is specialized in the development, production and sales of atomic fluorescence spectrometer High-tech enterprises. In the 1980s, the research group of Professor Guo Xiaowei of Northwest Nonferrous Geological Institute completed the research and development of hydride generation atomic fluorescence spectrometer technology, and then commissioned relevant enterprises to produce and realize the commercialization of atomic fluorescence spectrometer. On the basis of this in the 1990s, Xi'an Sokun Technology Development Co., Ltd. was established, with Professor Guo Xiaowei as the company's chief engineer. In order to expand the detection elements, increase the detection speed, and strengthen the stability of the test, Professor Guo Xiaowei led all the company's researchers to develop the flame atomic fluorescence spectrometer, continuous flow hydride generation atomic fluorescence spectrometer, and flame method-hydrogenation combined with atomic fluorescence technology . SK series products have four major features: multiple detection elements, fast testing speed, good technical indicators, and less trouble and consumables.

Hydride generation atomic fluorescence spectrometer can be widely used in the detection of arsenic, mercury, selenium, cadmium and other elements in environmental samples. Facing the test of low content of mercury in water and soil, how to effectively use the two-point standard curve correction technology to avoid the impact of data drift? What are the differences between two-dimensional and three-dimensional adjustments in the process of debugging an atomic fluorescent hollow cathode lamp? How to extend the service life of hollow cathode lamps as consumables when the sample test volume is not large? What details should be paid attention to in the pretreatment process of testing mercury in surface water, sewage and other samples?
Hydride generation atomic fluorescence spectrometer can be widely used in the detection of arsenic, mercury, selenium, lead, cadmium and other elements in food. When faced with many complicated food samples, as an experimenter, have you encountered the following headaches? Grains, milk and other samples generate a large number of bubbles during the hydrogenation reaction to affect the stability of the test; mercury in the sample exceeds the standard, serious memory effects cause pollution and difficult to clean; in the face of new food standards, expand inorganic arsenic and methylmercury testing items, liquid How can the phase chromatography and atomic fluorescence be upgraded to perform the speciation analysis of these elements?
The hydride generation atomic fluorescence spectrometer was first developed as a device specially developed for the detection of arsenic, antimony, bismuth and mercury in geological samples. Today, atomic fluorescence has become an indispensable analytical instrument for detecting geochemical samples in geological laboratories. Do you still have concerns and do n’t know how to deal with the following problems? When the arsenic and antimony elements in the sample are measured at the same time, how to ensure the accuracy of the data when the concentrations of the two are greatly different? In the case of batch testing, how to improve the detection efficiency of atomic fluorescence? Can it effectively solve the effects of drift when testing mercury? Can gold really be detected by atomic fluorescence, and can the sensitivity meet the test requirements?
Atomic fluorescence spectrometer can be widely used in the detection of arsenic and mercury in research projects of scientific research institutes, and it can also be used in basic teaching routinely. For the atomic fluorescence spectrometer used in scientific research, from which main aspects should the instrument be evaluated to ensure the reliability of the test data? In the face of many atomic fluorescence spectrometer products, how to effectively verify the performance and indicators promoted by the instrument? For teaching applications, from which aspects do you judge whether the instrument is simple to operate, easy to maintain, and consumable? Under what circumstances can the hydrogen flame method be used in combination with atomic fluorescence spectrometer to detect more elements in the sample instead of the combination of atomic fluorescence and atomic absorption?
