| 摘 要： | 基于电喷雾离子源(ESI)中液流的输运行为,构建了相应的物理模型,并利用Fluent软件对电喷雾离子源中带电液滴的形成与裂变过程进行模拟研究.分别考察了毛细管电压、离子源温度和溶液表面张力3个参数对源内液滴粒径分布的影响.模拟结果表明,较大的毛细管电压、较高的离子源温度和较低的表面张力条件下得到的液滴粒径较小,液滴碎裂效果较好.模拟结果与文献报道及经验公式结果一致.

| Abstract: | The Fluent software was used to simulate the formation and fission of charged droplets in electro-spray ion source based on the transport behavior of liquid in electrospray ion source(ESI) and constructed. The influence of the capillary voltage, ion source temperature and surface tension on droplet size distribution was studied. The results indicate that high capillary voltage, high source temperature, and low surface tension lead to smaller charged droplets and better breakup, which is in consistency with the study in published literatures and the calculation with empirical formula in this work. |
