With the development of science and technology, sensitive, rapid, reproducible, simple and accurate analytical methods are required for the determination of trace elements in geological, biological and environmental samples. The direct determination of extremely low concentration of trace element with modern atomic spectroscopic method, such as atomic absorption spectrometry is so difficult. On one hand, the limitations are associated not only with the insufficient sensitivity of these techniques but also with matrix interference.

随着科学技术技术的发展，在进行地质、环境、生物等样品中痕量金属元素的测定时，常常要求达到ppb级的水平，虽然火焰原子吸收分光光度法具有很高的灵敏度，但是要直接测定这些样品中的痕量组分却很难，这是因为，一方面，样品本身的物理化学状态有的不适合直接测定，或组分的含量低于分析方法的灵敏度；另一方面是存在基体干扰。
