Dm2500 mmedxrf light and medium element spectrometer Introduction: Dm2500mmedxrf light and medium element spectrometer is an innovative XRF spectrometer developed and launched by our company based on the company's original DM series X-ray fluorescence calcium sulfur iron analyzer, X-ray fluorescence multi-element analyzer, X-ray fluorescence spectrometer, etc. It uses multi monochromatic excitation energy dispersive X-ray fluorescence analysis technology. The main components, such as: the monochromatic crystal adopts the logarithmic spiral rotation point-to-point focusing germanium monochromatic crystal developed by our company and patented by our company; the X-ray tube adopts the 50W micro focus large radiation angle thin beryllium window X-ray tube produced by keyway company, and its high voltage, current and target materials are optimally combined; the X-ray detector adopts the X-ray detector produced by German Ketek company with high counting rate, high energy resolution SDD semiconductor X-ray detector with high transmittance at room temperature. In addition, the unique technologies such as the special optical system for light elements with independent intellectual property rights of the company and multiple monochromatic excitation systems used in combination with various methods have greatly improved the sensitivity and peak to back ratio of the instrument. It also adopts X-ray downward irradiation system and sample spin device, which is especially suitable for powder tablet samples, and can select vacuum system or self inflating system according to application. Thus, the spectrometer has reached the international leading level. In the comparison test with large wavelength dispersion spectrometer, most of its performance indexes are close to or reach the performance indexes of large wavelength dispersion spectrometer, and some even exceed. Its performance index is better than that of imported similar products, and the price is only half of that of imported similar products, with unparalleled price performance ratio. In addition, the convenience of after-sales service of domestic enterprises is unmatched by foreign enterprises. In addition, the good shielding design of the spectrometer ensures that there is no radiation leakage and meets the radiation exemption requirements. Features: 1. fast simultaneous – the required measured elements are analyzed rapidly at the same time, and the content results are generally given in tens of seconds. 2. high accuracy - the advanced mmedxrf technology and lsdcc core technology are adopted to select the energy of monochromatic light and the method of generating monochromatic light according to the elements to be measured, which greatly improves the sensitivity and peak to back ratio of the instrument, with excellent repeatability and reproducibility and high accuracy. 3. downward irradiation - the X-ray downward irradiation system is used to eliminate the possibility of sample powder pollution and damage to the detection system, especially suitable for powder samples such as cement raw clinker. 4. sample spin – it has a sample spin device, which eliminates the sample nonuniformity caused by the presence of extremely hard substances in the pressed sample and is not easy to crush. 5. long term stability – it adopts variable gain digital multichannel, and has the functions of PHA automatic adjustment, drift correction, deviation correction, etc., with excellent long-term stability. 6. environmental protection and energy saving - ray protection meets the exemption requirements. No contact, no damage to samples, no pollution, no chemical reagent, and no combustion during analysis. 7. easy to use - touch screen operation. After the sample crushing tablet is put into the instrument, just press the [start] key to truly realize one key operation. 8. high reliability - integrated design, high degree of integration, strong environmental adaptability, strong anti-interference ability and high reliability. 9. high cost performance – no cylinder gas is required, and the operation and maintenance cost is extremely low. The price is half of that of similar foreign products. It is a real cost-effective product.
