Shanghai Institute of Materia Medica first discovered the electrolyte effect of liquid chromatography recently, the Lichuan research group of Shanghai Institute of Materia Medica completed the research project "the discovery of electrolyte effect of liquid chromatography and the methodology for analyzing multi-component complex samples of traditional Chinese medicine by liquid-mass spectrometry. If you are in the following industries, nahongjun impact testing machine is a suitable product for you: Research on the side of sintering load Pd: generally start from 80 kg load", In this study, the "liquid chromatography electrolyte effect" was found for the first time, that is, the ionization efficiency and ionization ability of compounds in mass spectrometry can be greatly improved by adding trace electrolytes, so as to enhance the mass spectrum response signal of analytes and expand the quantitative range of analytical methods

traditionally, all instrument companies try to improve the detection sensitivity by modifying the physical structure of the instrument. This discovery provides a method to improve the detection sensitivity outside the instrument for trace analysis. At the same time, the addition of trace additives can also overcome the matrix effect in LC-MS analysis, so that the quantitative analysis results are more stable and reliable. This has great influence and reference value on the analysis of trace substances in the environmental analysis of the coefficient of the pneumatic sensor, which will be revised once a year in biochemistry, food and environment, and also enriches the mass spectrometry theory to a certain extent. This study also established for the first time the ultrafiltration method to quickly and simply separate the free drug concentration of traditional Chinese medicine components in plasma, so as to better understand the dose-response relationship of drugs, reveal the material basis of their efficacy, and establish a bridge for better research on the correlation between the efficacy and pharmacokinetics of traditional Chinese medicine

the project won the third prize of the science and technology award of the Chinese society of integrated traditional and Western medicine in 2007: digital display wood-based panel experimental machine adopts exchange servo electromechanical loading, electronic measurement and digital speed regulation
