【Abstract】 The development of miniaturized and reliable on-site analyzers is of great significance for environmental monitoring, life and health protection, as well as food quality control in normal and emergency circumstances. Microplasma, characterized by its miniature size and low power consumption, has become the core technology for the development of miniaturized optical emission spectrometry(OES) systems. The present review discussed the very recent advances in miniaturized OES systems by using microplasma as the excitation source. It provided special emphasis focusing on the structure and functions of dielectric barrier discharge, point discharge,and atmospheric pressure glow discharge microplasma excitation sources. In addition, pertinent descriptions were dedicated to the efficient sampling strategies of different phases. The integration and miniaturization progress of microplasma based OES systems were also discussed. Finally, the applications of miniaturized OES system in the field analysis for environmental monitoring, biological analysis and food safety assay were drawn. Meanwhile, the limitations, challenges and some of the currently unsolved technical issues in the future development of microplasma based OES systems were thoroughly discussed, along with potential key procedures for alleviating the related issues.更多还原
