摘要
采用GC-900气相色谱仪、3%PEG-12000/Chromosorb880AWDMCS填充柱和FID检测器,以水杨酸甲酯为内标物测定N-氰基乙亚胺酸乙酯含量,回收率在98.5%—101.8%之间,标准偏差为0.27%,变异系数为0.27%。
A method is desc ri bed for the determination of N-cyanoethanimidic acid ethyl ester by GC on3%P EG-12000/chromosorb880AW DMCS column and using methyl salicylate as in ternal standard?The relative standard deviation was0.27%,the coefficiency of variation was0.27%and the average recoveries was98.3%-101.2 %?
