本文在相对灵敏度理论基础上,提出以空气作相对标准的气相色谱定量方法,并引进空气标定因子作为应用这一方法的定量参数。有关气体在热导池检测器中的空气标定因子,根据Novak提出的相对克分子响应关系式计算得到的结果,其准确度可以满足一般情况下热导池气相色谱定量分析的精度要求。
Based on the relative sensitivity theory, this paper proposes a gas chromatographic method using air as a relative standard, and introduces air calibration factor as a quantitative parameter to apply this method. The air calibration factor of the gas in the thermal conductivity detector is calculated according to Novak’s relative molecular response. The accuracy can meet the accuracy requirement of the gas chromatographic analysis of the thermal conductivity cell under normal circumstances.
