摘要
建立气相色谱法测定烷基酰胺甜菜碱(CAB)中3-二甲氨基丙胺(DMAPA)含量。采用毛细管柱、火焰离子化(FID)检测器,标准曲线的线性相关系数为0.9998,检测限为0.2 mg/L。样品检测的平均加标回收率在90%～106%之间,能满足工业分析要求。
Determination of residual 3-（Dimethylamino）propylarnine （DMAPA） in Cocoamido Propyl Betaine（CAB） by Gas chromatography. In this method, the standard curve of the linear correlation coefficient was 0.9998 and the detection limit was identified as 0.2 mg/kg by capillary column and flame ionization detector （FID）; The recovery of adding standard sample for DMAPA were 90 %- 106 %. It shows that this method meets the requirements of industrial analysis.
