介绍营养补充品中刺激剂的毛细管气相色谱和气相色谱质谱联用检测方法。试样采用碱提 ,液 -液分配提取 ,以HP - 5毛细管柱为分离柱 ,用氮磷检测器测定。实验结果表明 :该方法操作简便 ,分析速度快 ,结果可靠。添加平均回收率为 75 4 %～ 14 3 1% ,相对标准偏差为 0 2 7%～ 5 5 % ,检出限为 5～ 4 0 μg/L。 The introduction of nutritional supplements stimulate the capillary gas chromatography and gas chromatography-mass spectrometry detection method. The samples were extracted by alkali and liquid - liquid. The HP - 5 capillary column was used as the separation column and the nitrogen and phosphorus detector was used for determination. Experimental results show that the method is simple, fast and reliable. The average recoveries were 75 4% -14 3 1%, and the relative standard deviations were 0 27% -55%. The limits of detection were 5 ~ 40 μg / L.
