摘　　要：ICP(电感耦合等离子体)离子源是目前质谱分析中最常用的离子源之一,具有电离效率高、分析产物主要为单电荷离子等特点。因其优良的性能,现已广泛应用于不同行业中。为了继续提升ICP-MS(电感耦合等离子体质谱)的分析性能,拓宽应用领域,许多学者通过实验研究,建模仿真对ICP离子源进行了深入研究。本文对这些工作进行了阐述,介绍了不同的影响因素对等离子体特性的影响。如气体流速、功率大小、采样深度等,并对有无质谱采样接口时的等离子体的特性进行比较,为优化等离子体离子源提供思路。Inductively coupled plasma(ICP) ion source is one of the most commonly used ion sources in mass spectrometry. It has the characteristics of high ionization efficiency and single-charged ions. It is widely used in different industries at present. In order to improve the analytical performance of inductively coupled plasma mass spectrometry(ICP-MS) and broaden its application fields, many scholars have conducted in-depth research on ICP ion sources through experimental research, modeling and simulation. These works are summarized and the effects of different influencing factors on plasma characteristics, such as gas flow rate, power, sampling depth, etc., are introducad, and the characteristics of plasma with or without mass spectrometry are compared to optimize the design of plasma ion sources.
