In the past ten years, heavy metal pollution incidents in China have been on a high-risk situation. The consequences of heavy metal pollution in the soil and subsequent ingestion into plants or immersed in groundwater bodies have caused adverse health effects. On January 10, Beijing Anke Huisheng Technology Co., Ltd. was released to the public. After three years of scientific research, the scientific and technical personnel of the company successfully developed a new type of X-ray fluorescence spectrometer PHECDA-MINI, which will become a rapid screening for contaminated sites. And key breakthroughs in pollution accident emergency monitoring. Not only does it significantly reduce the workload, but it also reduces monitoring costs. According to the survey results of soil pollution in the country, heavy metal pollutants are generally detected in various soils. The national total soil exceeding standard rate is 16.1%, of which inorganic pollutants exceed 82.8%. Therefore, the rapid screening of heavy metals in the soil has become the direction of major domestic and foreign analytical instrument manufacturers. However, due to the heavy metal analysis and detection equipment, long-term dependence on imported instruments and equipment has become the main profit growth point for analytical instruments companies in Europe and America. Especially X-ray fluorescence spectrometer, which is one of the means of analysis of heavy metal elements in the soil, and the double curved surface crystal is a key technology for improving the performance of the X-ray fluorescence spectrometer, but this technology has long been mastered by an analytical instrument company in the United States. And blockade. To this end, Beijing Anke Huisheng Technology Co., Ltd. has been conducting scientific research since 2015. Today, it has successfully developed the key component of the X-ray fluorescence spectrometer, the all-focus hyperbolic curved crystal, and it has become the second company in the world to possess this item. The technology company, based on this core technology, became the first company in the world to successfully develop a portable X-ray fluorescence spectrometer for the detection of soil heavy metal contamination limits. It is understood that the all-focus hyperbolic bending crystal is the core component of X-ray fluorescence spectroscopy and diffraction. The adoption of this technology can not only greatly improve the performance of the X-ray fluorescence spectrometer, but also monochromate and focus the X-ray tube exit spectrum. Sample test point. At the same time, it reduces the background of the scattered radiation, enhances the intensity of the fluorescence signal of the element, and greatly increases the analytical sensitivity of the X-ray fluorescence spectrometer, enabling the ability to analyze trace or trace samples. "The successful development of this technology has expanded the application of X-ray fluorescence to the food safety and environmental protection industries, changed the traditional analysis methods, and improved laboratory analysis capabilities." The company's official said that after the introduction of the spectrometer, not only Due to the widespread concern of the industry, cooperation has been established with the Ministry of the Environment, the Ministry of Agriculture and other environmental agencies.
