Determination of Pyridine in Water by Purge and Trap Coupled with GC-MS

建立了吹扫捕集气质联用法测定水中吡啶的方法,优化了前处理方法,该方法的操作简便安全,回收率在90%-110%之间,方法的检出限为0.1μg/L,结果表明,本方法适用于水中吡啶的检测要求。

A method for the determination of pyridine in water by using purge and trap coupled with GC - MS was established. The recoveries of pyridine was between 90% and 110%. The detection limits of pyridine was 0. 1ug/1. The Method is convenient and repeatable, and could meet the requirements of the determination of pyridine in water.
