摘要
针对电感耦合等离子体质谱法(ICP-MS)存在的两类干扰现象,总结了多原子离子、氧化物、双电荷、氢化物和同量异位素等质谱干扰及其消除的技术方案和基体效应、物理效应等非质谱干扰及其消除的技术方案;探讨了目前干扰消除存在的主要问题以及可能的解决方案;指出鉴于测试中干扰类型出现的多样性及复杂性,综合多种技术方案是干扰消除较为有效的途径。最后,对ICP-MS分析中干扰研究的发展前景做了展望。
For the analysis of two types of interference with inductively coupled plasma mass spectrometry(ICP-MS),the mass spectral interference and its cancellation technical plan,such as polyatomic ions,oxides and double charges and hydrides and heterotope are summarized.Meanwhile,the non-mass spectral interference and its cancellation technical plan,including matrix effect and physical effect,are discussed.In addition,this paper discusses the major problems and possible solutions of interference cancellation,and points out that integrating various plans is an effective way to eliminate interference.Finally,this paper puts forward the prospects of study on interference in ICP-MS.
