微波等离子体炬在材料和化学分析中有着广泛的应用。研究了一种同轴电极微波诱导等离子体炬（CE-MIP），使其可用于玻璃表面改性和抛光。专用喷嘴被设计成将二次气体注入到主等离子体射流中。本研究详细介绍了适应CE-MIP技术的表征过程。微波频谱分析用于创建从同轴电极发射的微波能量的极坐标图，其中微波能量与气体耦合以产生等离子体射流。光学发射光谱分析也被用来创建等离子体射流内的光子强度分布的空间地图，当不同的额外的气体被注入到it. CE-MIP火炬的表面能改性玻璃上，它创建一个超亲水性表面进行实验测试。
Microwave induced plasma torches find wide applications in material and chemical analysis. Investigation of a coaxial electrode microwave induced plasma (CE-MIP) torch is conducted in this study, making it available for glass surface modification and polishing. A dedicated nozzle is designed to inject secondary gases into the main plasma jet. This study details the adaptation of a characterisation process for CE-MIP technology. Microwave spectrum analysis is used to create a polar plot of the microwave energy being emitted from the coaxial electrode, where the microwave energy couples with the gas to generate the plasma jet. Optical emission spectroscopy analysis is also employed to create spatial maps of the photonic intensity distribution within the plasma jet when different additional gases are injected into it. The CE-MIP torch is experimentally tested for surface energy modification on glass where it creates a super-hydrophilic surface.
