2,4,6-三氯酚内标峰高定量气相色谱法,使用热导池检测器。柱填充物为:10%Reoplex400(重量比)加1.2%H_3PO_4(85%水溶液)涂于Chromosorb W-AW DMCS 60～80目担体上。内标为邻苯二甲酸二乙酯。分析结果的相对误差小于±1%;标准方差δ=0.2258。苯酚氯化产物的气相色谱分析一般多采用面积归一化定量。当产品在处理过程中带进不能出峰的物质时,这种方法就不宜应用。本文采用内标法对2,4,6-三氯酚的定量进行了研究。结果如下:
2,4,6 - trichlorophenol internal standard peak high - volume gas chromatography, the use of thermal conductivity detector. Column packing: 10% Reoplex 400 (by weight) plus 1.2% H 3 PO 4 (85% aqueous solution) was applied to Chromosorb W-AW DMCS 60 ~ 80 mesh support. Internal standard is diethyl phthalate. The relative error of the analysis results is less than ± 1%; the standard deviation δ = 0.2258. Gas chromatographic analysis of chlorinated products of phenol generally use area normalized quantitative. This method should not be used when the product is brought into the unprotonable material during processing. In this paper, the internal standard method of 2,4,6-trichlorophenol quantitative study. The result is as follows:
