| 摘 要： | 阐述了一种利用气相色谱-质潜联用（GC—MS）法测定月桂酸二乙醇酰胺含量的方法。样品直接用甲醇或丙酮溶解并稀释争质量分数约0．4％后，用GC-MS扫描分析定量，并将其测定值和国家标准GB／T15046-94分析结果进行对比。实验结果表明，该办法相对标准偏差为0．38％，测定结果与GB／T15046—94方法的分析结果基本一致。该方法样品处理简单、快捷，分析速度快，定量准确，适用于不同类型烷基醇酰胺产品。

| Abstract: | A method for the determination of lauric acid diethanolamide by gas chromatography - mass spectrometer （GC-MS） is expounded. The sample dissolved directly in methanol or acetone and diluted to approximate 0.4%. Quantification of lauric acid diethanolamide was made by GC-MS method. The data were compared with that of GB/T 15046-94, and the results showed that concurrent data were obtained by two methods. The relatively standard deviation of this method is 0.38%. This method is simple and rapid in sample treatment, quick in analysis, accurate in quantification, as well as suitable for different type of alkyl alcohol amide products. |
