Bisphenol A is a widely used chemical raw material. Because of bisphenol A has a higher boiling point and strong polarity, and heated to 150 DEG C that is beginning to break down, so directly by gas chromatography analysis, chromatographic peaks are seriously tailing, groups of trace points or even no peak and impurity peak resulting from the decomposition. A positive phase high performance liquid chromatography was used to analyze the process, but the process of analysis was consumed.
Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus gas chromatograph (GC) with chemical derivatization method for methylation of bisphenol a specimen, by capillary gas phase chromatography of methyl samples for quantitative analysis, phenolic impurities in bisphenol a qualitative and quantitative results
双酚Ａ是一种用途广泛的化工原料。由于双酚Ａ具有较高的沸点和较强的极性 ,并且加热至15 0℃时即开始分解 ,因此直接用气相色谱法进行分析时 ,色谱峰严重拖尾 ,微量组分甚至不出峰 ,同时有分解产生的杂质峰出现。有人采用正相高效液相色谱法进行分析 ,但分析过程要消耗
滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱仪，采用化学衍生的方法对双酚A试样进行甲基化处理 ,用毛细管气相色谱法对甲基化试样进行定量分析 ,得到了双酚A中酚类杂质的定性、定量结果
