圆盘固相萃取-GC/MS/SIM法在水体有机氮磷农药测定中的应用研究

Application Study of SPE Disks and GC/MS/SIM Method in Determining Nitrogen and Phosphorous Pesticides

通过有机氮磷农药测定的样品前处理技术圆盘固相萃取、GC/MS的测定技术选择离子跳变扫描SIM的应用研究,建立了水体中有机氮磷的分析测定方法.其方法检出限达到了ng/L级的水平.

An analytical method of determining nitrogen and phosphorous pesticides in water!was proposed by studying the pretreatment technique of SPE disks and the determination technique of GC/MS/SIM. The detect limits were up till ng/L level.
