两款原子吸收光谱仪的塞曼背景校正装置

摘要

The new technology of the Zeeman-effect background correction atomic absorption spectro-photometer (ZAAS) in China was introduced. A new optical path design and new technology of permanent magnetic field ZAAS were discussed. A new system for simultaneous achieved Zeeman-effect background correction signals in AC/DC magnetic field was described. The power supply system was designed for eliminating the influence of Lorentz Force in magnetic field and graphite furnace.%讨论了永久磁场塞曼背景校正原子吸收光谱仪的外光路和磁场的设计工艺,描述了可以同时获得交流磁场和直流磁场塞曼背景校正测定结果的新系统,以及可以克服洛伦兹力对测定产生影响的磁场和石墨炉的供电系统.
