原子吸收光谱分析是现代分析技术中应用较多的分析方法,其基本原理是根据元素的吸光度与元素的含量成正比关系进行分析的,由于测量的环境和基体组份不同,即使相同含量的样品测得的吸光度可能偏大或偏小,因此,最后测量结果的准确度也不相同,选取不同的定量方法,成为决定测量结果的精确程度的关键因素。 Atomic Absorption Spectroscopy (AAS) is an analytical method widely used in modern analytical techniques. The basic principle is that the absorbance of an element is directly proportional to the elemental content. Since the environment and the matrix components are different, even the same amount of sample The measured absorbance may be too large or too small, so the accuracy of the final measurement results are not the same, choose a different quantitative method, the determination of the accuracy of the measurement of the key factors.
