标准气浓度对定量误差影响的探讨王武明，宫润娥（中国科学院大连化学物理研究所大连１１６０１２）１前言在高纯气体分析中，标准气是分析准确度的基准。为减少定量误差，通常认为标准气的浓度应接近于待测样品的浓度，钢瓶装标准气使用方便，但浓度却是固定的。用动态指...
n the trace gas analysis,experimental results show that the relative error can be kept in the range of±10% even in case where the difference in concentration between the standard mixture and sample gas is up to100 times.When the exponential dilution is used for calibration,the standard mixtures of higher concentra-tion with less period of time in the dilution procedure give quite accurate data.
