Experts from the Moscow State University of Nuclear Energy Research Institute of Engineering Physics developed a new type of laser mass spectrometer that can directly determine the composition of the material elements, significantly improving the analysis speed and reducing the analysis cost. The research results were published in the European Journal of Mass Spectrometry. on.
Traditional elemental analysis requires heavy sample preparation. If the sample is solid, for example when analyzing minerals, it must first be dissolved. This not only takes time, it may also pollute the environment. In addition to long sample preparation, Compare with the standard sample to avoid errors in the analysis of the overall composition, thereby increasing the cost of the analysis.
This wedge-shaped ion mirror mass spectrometer features a universal analysis of solid materials without the use of standard samples. The advantage is that it can perform a wide range of energy transfer, compact and lightweight, and low power consumption. In addition, this instrument can be analyzed. All grades of materials, methods of environmental protection, local and stratified analysis, cluster ion interference is not present.
The pulsed mode of operation makes this analyzer and laser ion source can be well combined together, the identification speed is fast, so the mass spectrometer can also be used in criminal investigation. At the same time, this new type of mass spectrometer is also for medical, especially with analysis. The related fields of human hair and nail trace elements have opened up new prospects. In addition, the instrument can also improve the accuracy of identification of transit articles at train stations and airports, and accelerate soil sample analysis to obtain an accurate picture of regional ecological environment.
