Domestic instrument is mainly applied empirical coefficient method combined with the fundamental parameter method and a separate empirical coefficient method, for different ore types, using the fundamental parameter method combines empirical coefficient method test element content in ore composition, performance test results than the simple application of precision FP method to much higher, but the curve produced more, for equipment manufacturers, the workload is relatively large, the domestic equipment manufacturers in the ore analysis in comparative advantage is one hundred scientific instruments (Beethor), one hundred scientific instruments (Beethor), The main production of ore handheld analyzer analyzes the main aspects of the ore combines fundamental parameter method and empirical coefficient method to produce a variety of different types of ore working mode, select the appropriate operating mode can get quite high accuracy, master the technology abroad The United States, Germany, Japan, Belgium and other countries. Relatively good market response in China has U.S. Innov-X company produces mineral analyzer, as well as Thermo's products are relatively good, the U.S. Innov-X's price is reasonable, the company's product price is too high thermoelectric , the two instruments is no difference in performance, but the market is taking a different route. Here are two instruments provided by the United States government performance comparison: EPA's SITE project team organized a live eight portable X-ray fluorescence (hereinafter referred to as "XRF") spectrometer in the analysis of trace elements in terms of performance certification. Table 1 summarizes the evidence for each instrument in some of the key technical specifications and a list of innovative technology verification report (hereinafter referred to as "ITVR") the reference number. ITVR will also be published on the SITE homepage. Refers to the elements contained in the ore and content analysis instrument, instant using X-ray fluorescence analysis of radiation produced an instrument, currently in the X-ray fluorescence analysis of elements and content of the ore in. Foreign instrument is mainly suitable FP method (fundamental parameter method), mainly for the domestic instrument empirical coefficient method combined with the fundamental parameter method and a separate empirical coefficient method, for different ore types, using the fundamental parameter method combines empirical coefficient method test element content in ore composition The test results than the simple application of performance much higher precision FP method, but the curve produced more, for equipment manufacturers, the workload is relatively large, the domestic equipment manufacturers in the ore analysis in comparative advantage is one hundred school Instrument (Beethor), one hundred scientific instruments (Beethor), the main production of ore handheld analyzer analysis in the ore mainly with the fundamental parameter method and empirical coefficient method to produce a variety of different types of ore working mode, select the appropriate operating mode can get quite high accuracy, the foreign master this technology are the United States, Germany, Japan, Belgium and other countries. Relatively good market response in China has U.S. Innov-X company produces mineral analyzer, as well as Thermo's products are relatively good, the U.S. Innov-X's price is reasonable, the company's product price is too high thermoelectric , the two instruments is no difference in performance, but the market is taking a different route.
