【Abstract】 Objective To detect the tetramine in poisoned food.Methods Tetramine of poisoned samples was extracted by acetonitrile (or dichloromethane) isolated by HP-5MS(low-bleed,5%diphenyl-and 95% dimethyl-polysiloxane) silica capillary column,and identified by mass spectrometer.Results The concentration of tetramine was the ranged from 1 0 to 8 0 μg·ml -1 with well linear relation.The relative coefficient is 0 9990.The detectability of the method is 1.0ng.The average recovery rate is 98% to add tetramine into the samples.Conclusion The proposed method has been applied to the analysis of poisoned food with satisfactory results.更多还原
