中文摘要: 利用 LC-MS/MS 建立大米中噻虫嗪农药测定的方法。 试样中噻虫嗪农药残留在超声波振荡条件下用乙腈提 取， 经 C18 和 PSA 进行分散固相萃取净化， 经液相色谱质谱联用仪检测。方法的检出限为 0.1 μg/kg， 回收率为 93.5 % ~ 101.2 %，相对标准偏差为 3.12 % ~5.84 %。
Abstract:The method for determing thiamethoxam in rice has been build utilizing LC-MS/MS technique. The pesticide residues in rice samples were extracted with acetonitrile and by ultrasonic， thiamethoxam were cleaned-up by C18 and PSA as purification sorbent， determined by LC-MS/MS. The lim its of detection were 0.1 μg/kg. the average recoveries for The pesticides ranged from 93.5 % to 101.2 %， with the relative standard deviation（RSD）between 3.12 % and 5.84 %.
