电感耦合等离子体光/质谱中的进样技术

Introduction Technique in Inductively Coupled Plasma Optical Emission Spectrometry/Mass Spectrometry

电感耦合等离子体原子发射光谱/质谱(ICP-OES/MS)技术因具有灵敏度高、动态线性范围宽、分析速度快以及多元素同时检测等综合优势,在痕量/超痕量元素分析中占据主导地位,但进样技术直接决定着ICP-OES/MS的分析性能和应用范围.基于该方法自创建以来的研究发展,根据样品存在状态和物理性质的差异,把ICP-OES/MS分析的进样技术分为气体进样技术、液体进样技术和固体进样技术三类并进行相关对比评论.以期给潜在用户提供仪器配置选择参考和给专业研究者提供文献信息.

Inductively coupled plasma optical emission spectrometry/mass spectrometry（ICP-OES/MS） is considered one of the most suitable instrumental techniques for determination of trace/ultra-trace elements and elemental species analysis in different samples owing to its excellent analytical performance,such as multi-element capability,wide linear dynamic range,low detection limit and good precision.It should be pointed out that sample introduction technique exerts a vital effect on analytical performance of ICP-OES/MS and its applied field.Based on researches and developments of ICP-OES/MS since its creation,this paper classed the introduction technique of ICP-OES/MS into gas,liquid and solid introduction technique according to sample type and their physical character difference.The purpose of the paper is to provide reference to equipmental apparatus choice for potential customers and literature information for specialized researchers.
