| Abstract: | Gas Chromatography-Mass Spectrometry(GC-MS) is set up to analyze the content of N-Dimethylnitrosamine in salty fish.Samples are extracted with acetone/dichloromethane(1∶2),and determined by SIM.The pre-treatment of the samples is simple and rapid.The liner range of the method is 0~500 μg/mL,the average recoveries are 84%～90.3%,the relative deviations are 2.4%～4.0%,the detection limit is 0.6 ng/g.Therefore this method could be used to detect the content of N-Dimethylnitrosamine in salt fish in the market. |
