原子吸收光谱分析中一种新的背景校正方法

A New Method for Background Correction in Atomic Absorption Spectroscopy Analysis

作者提出一种新的原子吸收光谱分析的背景校正方法。通过LPDA波长分辨技术,在光源原子发射谱线轮廓内不同波长位置测量相应的吸收系数进行背景校正,本方法不需任何校正装置硬件,仅用软件处理获得结果。

The paper reports a new background correction method in AAS. With LPDA wavelength resolution tcchnique, there is no need for background correction device, but computer software. The corrcction error resulted from timc difference of two measurements is two orders of magnitude less than that of the other methods.
