目的应用气相色谱质谱联用技术同时检测蔬菜中多种氨基甲酸酯类农药。方法用振荡器和样品浓缩仪优化样品前提取方法,以气质联用仪分析氨基甲酸酯农药。结果该方法相对标准偏差在2.73%～5.09%之间,回收率在81.8%～95.6%之间,线性相关系数大于0.9957。结论该方法准确可靠,可应用于蔬菜中多种氨基甲酸酯农药的同时测定。 Objective To simultaneously detect a variety of carbamate pesticides in vegetables by gas chromatography-mass spectrometry. Methods Oscillators and sample concentrators were used to optimize the method of sample pre-extraction and the carbamate pesticides were analyzed by GC / MS. Results The relative standard deviations (RSDs) were between 2.73% and 5.09%. The recoveries ranged from 81.8% to 95.6%. The linear correlation coefficients were greater than 0.9957. Conclusion The method is accurate and reliable and can be applied to the simultaneous determination of various carbamate pesticides in vegetables.
