目的 研究毒鼠强的测定方法。方法 毛细管柱气相色谱法 :火焰光度检测器 ,硫滤光片 ,中等极性毛细管柱 ,程序升温 ,起始温度 2 10℃ ,1min ,以 10℃ /min速率升至 2 4 0℃ ,保持 5min ,进样器温度 2 5 0℃ ,检测器温度 2 6 0℃。结果 检出限 1.5× 10 -10 g.s-1、精密度RSD 0 .5 9%、重复性RSD 1.6 %、测量范围 10~2 0 0ng ,8种有机硫农药不干扰测定。结论 本方法能满足日常卫生检测的需要。 Objective To study the determination of tetramine in rats. Methods Capillary gas chromatography: flame photometric detector, sulfur filter, medium polarity capillary column, programmed temperature, initial temperature 2 10 ℃, 1min, with 10 ℃ / min rate rose to 240 ℃, hold 5min , The injector temperature is 250 ℃ and the detector temperature is 260 ℃. Results The detection limit was 1.5 × 10 -10 g · s-1, the precision RSD was 0.59%, the repeatability of RSD was 1.6% and the measurement range was 10 ~ 200 ng. The 8 organosulfur pesticides did not interfere with the determination. Conclusion This method can meet the needs of daily health testing.
