原子吸收分析中标准曲线弯曲及其校直方法的探讨

DISCUSSION ON CURVATURE OF STANDARD CURVE AND CORRECTION IN ATOMIC ABSORPTION SPECTROMETRY ANALYSIS

本文从原子吸收分析中使用的光源、原子化系统及光学系统等方面阐述了原子吸收分析中造成标准曲线弯曲的原因，以及曲线校直的方法（如电子学方法、数学模型法等）。作者研制的数学模型法用于国产原子吸收光谱仪中，提高了原子吸收光谱仪的测量精度、稳定性和分析速度。

In this paper, the reasons for causing the curvature of the standards curve in the atomic absorption spectrometry analysis, are briefly described in the aspects of element lamp source, atomization system and optical system etc. The methods of correction, such as eletronics correction and mathematical modelling correction are introduced. The mathematical model developed by the author is used in a atomic absorption made in China. The precision, stability, analysis speed of atomic absorption spectrometer are increased.
