中文摘要	采用高效液相色谱-电喷雾电离-串联质谱(HPLC-ESIMS/MS)建立了同时测定谷物中草毒死、草净津残留量的分析方法. 样品经二氯甲烷提取, Oasis HLB固相萃取柱净化,采用C_(18)色谱柱(250 mm* 4.6 mm i.d., 5mum)分离,甲醇-0.1%甲酸溶液(体积比50:50)洗脱, ESIMS/MS进行测定. 草毒死、草净津的线性范围分别为0.02~10.0、0.01~10.0 mg/kg,相关系数分别为0.999 6、0.999 3,检出限分别为 0.01、0.005 mg/kg,平均加标回收率为80%~102%
英文摘要	A high performance liquid chromatography - electrospray ionization mass spectrometric (HPLC - ESI MS/MS) method was developed for the simultaneous determination of allidochlor and cyanazine in grain samples. Two herbicides were extracted from grains with dichloromethane, cleaned up on an Oasis HLB solid-phase extraction(SPE)column, separated on a C_(18) column (250 mm x4. 6 mm i. d., 5 mum) using methanol - 0. 1% formic acid(50 : 50, by volume) solution as mobile phase at a flow rate of 1. 0 mL/min, and then determined by ESI MS/MS. The method showed good linearities over the concentration range of 0. 02 - 10. 0 mg/kg for allidochlor with a correlation coefficient of 0. 999 6 and 0. 01 - 10. 0 mg/kg for cyanazine with a correlation coefficient of 0. 999 3. The detection limits for allidochlor and cyanazine were 0. 01 mg/kg and 0. 005 mg/kg, respectively. The average recoveries of two herbicides in spiked samples were between 80% and 102%
