摘要:
本文主要阐述了气相分子吸收光谱法测定硫化物时对其校准曲线斜率、截距参考值的分析。通过收集实验室近三年采用气相分子吸收光谱法测定硫化物时制作校准曲线的一系列原始数据，并用数理统计方法对校准曲线及其有关指标进行了详细讨论，得出气相分子吸收光谱法测定硫化物校准曲线的斜率参考值范围为：0.0961 ± 0.0013，截距参考值范围：−0.0018 ± 0.0030。此结果对实验室分析人员判定硫化物项目校准曲线制作是否合格具有一定的参考价值。
This paper mainly analyzed the reference value of the slope rate and intercept from the sulfide’s calibration curve by using gas-phase molecular absorption spectrometry. The calibration curve and its related indexes were discussed in detail by using mathematical statistics method through nearly three-year original data in laboratories. Results showed that the reference range of slope of the gas-phase molecular absorption spectrometry calibration curve is 0.0961 ± 0.0013, and that of intercept is −0.0018 ± 0.0030. These results provide reference for determining eligibility criteria of sulfide calibration curve.
