Guyan Reagents-Our scientists have developed the latest discoveries and innovations of portable intellectual property mass spectrometers with independent intellectual property rights. Food safety, environmental pollution ... Life is constantly testing the performance of analytical instruments "On-site, fast and portable" has become the focus of the domestic and foreign analyzer equipment research. Recently, a prototype of a portable mass spectrometer jointly developed by the Chinese Academy of Metrology and Tsinghua University was released in Beijing. This small instrument weighing less than 10 kg is considered to be in sync with similar foreign research levels. A mass spectrometer is an instrument that ionizes material particles into ions, separates them, detects their intensity, and performs qualitative and quantitative analysis. Because of its high sensitivity, high resolution, and direct measurement, it is widely used in many fields such as environmental monitoring, food safety, new drug development, and life sciences. In China, the analytical instruments and equipment represented by mass spectrometers have always had the problem of insufficient core technology, and the domestic mass spectrometer market has been monopolized by foreign companies. Starting from the "Tenth Five-Year Plan", China has set up related topics in the science and technology plan. This portable mass spectrometer is the result of the "Eleventh Five-Year Plan" technology support plan and "innovative methods". Based on the achievements of the research and development of "mass spectrometry instruments" during the "Tenth Five-Year Plan", the research team successfully achieved a series of innovative scientific and technological achievements through two teams with different technical advantages and characteristics. The key components of the portable mass spectrometer are independently researched and designed by the research team. The key components and the technical level of the whole machine are equivalent to similar foreign instruments. Experts believe that the core components of the portable mass spectrometer, the ion source and the mass analyzer, have independent intellectual property rights and obvious innovation: the instrument has a second-level mass spectrometry (MS / MS) tandem analysis capability, small size, and low power consumption; In addition, the instrument has the ability to directly analyze gas, liquid, and solid samples, enabling fast, in-situ analysis. Academician Zhang Yukui of Dalian Institute of Chemical Physics, Chinese Academy of Sciences said that the successful development of portable mass spectrometer will promote the development of China's mass spectrometer industry, and will also provide an advanced, on-site and rapid detection method for related fields.
