DHF81 fast multi-element analyzer Introduction I. Overview DHF81 fast multi-element analyzer based on photometric analysis based on the principle developed by the analyzer, using a unique method of linear expansion and increase sensitivity. Spectrophotometric analysis to solve the traditional high deviation from linear component content, low component content analyzed the problem of poor sensitivity. To achieve a large-scale, rapid analysis with high accuracy. 1994 to complete the eight elements of the system analysis, 2000 to complete the eighteen elements of the system analysis, completed in 2002 twenty elements of the system analysis. The analytical tools are the first at home and abroad, in silicate systems analysis in the field has a significant advantage, especially suitable for ceramics, refractories, cement, glass, geology, and other non-metallic mineral industries. The products in the universities, research institutes, industrial enterprises have been applied hundreds, both received good results, and has entered the bulk of the international market. Second, the main technical parameters 1. Measuring range 1.1 to measure oxide content and scope of the name name name content 0.1-99% silica content in the name of the content of aluminum oxide 0.1-99% ferric oxide titanium dioxide 0.1-99 0.1-99% % sodium hydroxide 0.1-99% 0.1-99% calcium oxide, magnesium oxide, 0.1-99% 0.1-99% 0.1-99% lithium oxide, zirconium oxide, 0.1 to 15% 1.2 measurement sample types feldspar, clay, kaolin, quartz, limestone, wollastonite, talc, dolomite, ceramic powder, glazes, frits, bauxite, alumina, aluminum, magnesium and other silicate, aluminate, calcium, high magnesium samples or ore. 2. Analysis accuracy: the accuracy of the analysis of the elements at or better than national standards allow error analysis method specified. 3. Analysis of Speed: start 2-3 hours to complete the amount claimed SiO2, Al2O3, Fe2O3, TiO2, K2O, Na2O, CaO, MgO full analysis. Analysis of other elements 4-6 hours to complete. 4.
