In order to compare the retention time ( rt ) and limits of detection of 20 organophosphorous insecticides in different conditions the experiments were carried out using a medium polar capillary column ( db - 1701 ) and a no polar capillary column ( db - 1 ) with two detectors ( gc - fpd and npd ) . the rt of 20 organophosphorous insecticides in two different polar capillary columns was a retention qualitative method for 20 organophosphorous insecticides . db - 1701 capillary column coupled with gc - fpd detector was used in the following study , the limits of detection were in range of 5x10 - 11 ~ 2x 10 - 12 g , the linear range was 2x 10 - 9 ~ 1 x 10 - 11g 本研究用两种检测器(氮磷检测器和火焰光度检测器仪器)和两种不同极性色谱梓(中极性毛细管色谱柱db - 1701 、非极性毛细管色谱柱db - 1 )作为研究手段，比较了20种有机磷杀虫剂在两种色谱柱( db - 1 、 db - 1701 ) 、两种检测器( fpd 、 npd )上的保留时间及最小检测量，建立了用不同极性色谱柱上有机磷农药的保留时间可作为有机磷农药双柱定性确证的的方法；建立了db - 1701 ， gc - fpd测定蔬菜中20种有机磷杀虫剂的气相色谱法，该方法的最小检测量为5 10 ~ ( - 11 ) 2 10 ~ ( - 12 ) g ，线性范围在2 10 ~ ( - 9 ) 1 10 ~ ( - 11 ) g时，相关性良好。
