自从Greenfield等及Fassel等把电感耦合等离子体应用于光谱分析,使得发射光谱分析取得了突破性的进展。ICP作为光谱化学分析常用的工具,有下列优点:(1)激发温度高;(2)能量密度大;(3)光学透明度好;(4)长期稳定性好。因此,用ICP分析样品时,样品解离完全;基体或元素间干扰小;具有较好的分析精度和准确度;工作曲线动态范围宽;检出限较低;稳定性好。ICP被公认为最有希望的激发光源之一。
Since Greenfield et al. And Fassel et al. Have used inductively coupled plasma for spectral analysis, a breakthrough has been made in emission spectroscopy. ICP spectrometry commonly used as a tool, has the following advantages: (1) high excitation temperature; (2) large energy density; (3) good optical transparency; (4) long-term stability. Therefore, when using ICP to analyze the sample, the sample dissociation is complete; the interference between the matrix and the element is small; the analysis precision and the accuracy are good; the dynamic range of the working curve is wide; the detection limit is low; the stability is good. ICP is recognized as one of the most promising excitation light sources.
