【摘要】 对气相色谱（ＧＣ）火焰光度检测器（硫）即ＦＰＤ（Ｓ） 有关的理论和实验问题进行了研究。理论分析表明，具有指数响应特征的ＦＰＤ（Ｓ） 检测器的峰高和峰面积定量有等效性；作为内标物，只有与被测物有相同的响应指数时才有意义。实验结果表明，对于双火焰ＦＰＤ，甲乙硫醚（ＥＭＳ）可用作二甲硫醚（ＤＭＳ） 的内标；峰高较峰面积定量好，指数非线性模拟比对数线性化模拟得到的结果更佳。更多还原

【Abstract】 Some theoretical and experimental issues regarding the response characteristics of the sulfur mode flame photometric detector (FPD-S) in gas chromatography are studied in this paper. It is demonstrated that theoretically, peak height and peak area are equivalent in the quantitative analysis of the detector which characterized in exponential response. As an internal standard, its FPD response exponent should be equal to that of the solute to be analyzed. Experiment results show that, for the equipment and conditions used in this study, ethylmethylsulfide (EMS) can be successfully used as an internal standard for precision control in the determination of dimethyl sulfide (DMS); peak height shows better fitness than peak area, and the exponential model gives better regression results than the linear model.更多还原
