解决原子吸收石墨炉法重复性差问题的探讨

Study on poor repeatability of determination by GF-AAS

结合多年实际应用原子吸收石墨炉法检测的工作体会,总结出引起石墨炉法检测重复性差的5个方面的原因,包括:元素谱图、石墨管、升温程序、进样针、样品的前处理,并提出解决办法,以此供相关工作者交流探讨。

Based on many years practical work experiences of determination by graphite furnace atomic absorption spectrometry. This paper analyzes five reasons for poor repeat ability of determination： elements spectra, graphite tubs, temperature program, injection needle, sample pretreatment methods, as well as the measures to solve it. That would serve as a reference for related workers.
