本文从理论和实验证明,色谱分析中热导检测器(简称 TCD)的相对校正因子与检测器构造.桥电流、池体温度、柱温、载气流速、固定相性能、进样量和组份含量等操作参数无关.在色谱分析测量误差范围内,文献里的相对校正因子可直接引用. In this paper, the theoretical and experimental results show that the relative correction factor of the thermal conductivity detector (TCD) and the detector structure in the chromatographic analysis are as follows: bridge current, cell temperature, column temperature, carrier gas flow rate, Content and other operating parameters has nothing to do in the chromatographic analysis of measurement error, the relative correction factor in the literature can be directly quoted.
