自从电感耦合等离子体发射光谱分析获得成功的文章发表以来,这一技术在地质、冶金、农业,生物和环境科学中已迅速地成为一种有力的分析工具。然而,现已表明它也存在各种形式的干扰。对于组成复杂的样品,共存物浓度的变化往往引起背景水平的变化。在许多例子中,共存组分的光谱线和带光谱对分析线的光谱重叠会使背景信号产生移动,另外,各种形式的杂散光也会使背景信号发生移动,由于这些干扰的存在,在测定复杂基体样品中的痕量元素时,很难选
This technique has rapidly become a powerful analytical tool in geology, metallurgy, agriculture, biology and environmental science since the successful publication of ICP-AES. However, it has now been shown that there are also various forms of interference. For complex samples, changes in the concentration of co-deposit tend to cause changes in the background level. In many cases, the spectral overlap of the coexisting components and the spectral overlap of the spectra versus the analytical line will cause the background signal to shift. In addition, the various forms of stray light also cause the background signal to shift. Due to these disturbances, Determination of complex matrix samples of trace elements, it is difficult to choose
