等离子体光谱进样系统乙醇溶液的雾化特性

Study on Performance of Sample Introduction System for an Ethanolloaded Inductively Coupled Plasma

实验研究了固定交叉雾化器和玻璃圆筒形雾室所组成的进样装置对乙醇水溶液进样时的雾化进样特性,测试了乙醇水溶液体系的物性参数,以及乙醇对试液的提升量、雾化率和分析物进炬率。

The effects of ethanol concentration on physical performances and nebulization characteristics in an ethanolloaded inductively coupled plasma system were studied. The sample introduction system was composed of a cyclone spray chamber and a crossflow nebulizer. The viscosity, surface tension and density for ethanol sample solution were examined. The experimental results showed that the velocity of sample aerosol into torch was increased when the ethanol was added into sample solution. It could improve analytical performance.
