电感耦合等离子体-质谱(Inductively coupled plasma-mass spectrometry,ICP-MS)中,以电感耦合等离子体(Inductively coupled plasma,ICP)作为质谱的高温离子源,样品由载气带入,通过蒸发、分解、原子化和电离等过程形成离子,然后通过样品锥接口和离子传输系统进入高真空质谱部分[1-2]。质谱是质量筛选和分析器,根据离子的质荷比(元素的质量数)进行分离分析,在一定的浓度范围内,元素的质量数所对应的
In Inductively coupled plasma-mass spectrometry (ICP-MS), inductively coupled plasma (Inductively coupled plasma, ICP) is used as a high temperature ion source for mass spectrometry. The sample is carried by a carrier gas and is decomposed by evaporation , Atomization and ionization process to form ions, and then enter the high vacuum mass spectrometry part through the sample cone interface and ion transport system [1-2]. Mass spectrometry is a mass screening and analyzer, according to the ion mass-to-charge ratio (elemental mass number) for separation and analysis, in a certain concentration range, corresponding to the mass of the element
