摘要
用电子捕获检测器，大孔径毛细管色谱柱直接进水样分析７种有机磷农药。柱容量大，分析速度快，分离效率高于填充柱，灵敏度高于火焰光度检测器。分析精密度和准确度均较小内径毛细管柱高。
The 7 kinds of organic phosphorus pesticides in injecting water sample wits Gas Chromatography equipped with ECD, large diameter capillary columu. The advantage of large diameter capillary column is large capacity,short time of analytical period, higher separation effect than parked column, better accuracy and precision than small diameter capillary. ECD is higher sensitive than FID.
