近年来,随着石墨炉原子吸收分析技术的发展和应用,使人们越来越深刻地认识到石墨管的性能对石墨炉原子吸收分析起着重要的作用,它直接影响分析方法的灵敏度、检出限和准确度。因此作者在进行石墨炉原子吸收法测钡时,同时观察了普通石墨管、热解涂层石墨管和全热介石墨管的性能,并将所得实验结果作了全面的比较。
In recent years, with the development and application of graphite furnace atomic absorption spectrometry, people have realized more and more profoundly that the performance of graphite tube plays an important role in graphite furnace atomic absorption spectrometry. It directly affects the sensitivity of the analytical method. Out of limits and accuracy. Therefore, when the graphite furnace atomic absorption method for the determination of barium, while observing the ordinary graphite tube, pyrolytic coated graphite tube and all thermal-mediated graphite tube performance, and the results obtained for a comprehensive comparison.
