塞曼效应用于原子吸收背景校正后,许多作者研究了其校正曲线的“翻转”(roll over)现象。也有作者对大量元素的曲线“翻转”作了实验研究,并对此作了理论解释,在解释中还考虑到分析线精细结构和超精细结构的影响。然而这些实验和讨论都忽略了杂散光来源和自吸等因素对校正曲线形状的复杂影响。本文仅就横向恒定磁场偏振分离调制方式商品ZAA仪器(CPMPM)中校正曲线的形状作进一步的研究和解析。
After the Zeeman effect was applied to the background correction of atomic absorption, many authors investigated the “roll over” of its calibration curve. Some authors also made an experimental study on the “flip” of the curve of a large number of elements and gave a theoretical explanation for this. In the explanation, the influence of the fine structure and the ultrafine structure of the line is also considered. However, these experiments and discussions have neglected the complex influence of the sources of stray light and self-priming on the shape of the calibration curve. This paper only further studies and analyzes the shape of the calibration curve in the commercial ZAA instrument (CPMPM) for the horizontal constant magnetic field polarization separation modulation.
