| 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. |
