Abstract

Mass spectrometer is one of the most versatile tools in current analytical science, which can perform both qualitative and quantitative chemical identification with high sensitivity, high accuracy and low consumption. Currently, the development of miniature mass spectrometer has received growing interest, since it provides a rapid way for online detection and real-time analysis. Quadrupole analyzer has been widely used in quantitative analysis, and it can be easily miniaturized for the purpose of developing portable mass spectrometers. A portable quadrupole mass spectrometer was developed for in-situ analysis, which can perform both qualitative and quantitative analysis for solid or liquid samples in atmospheric conditions.
