摘要

本报告描述了一种自动化固相萃取(SPE)装置的开发,该装置由50端口萃取装置(Aqualab)与包含C18速盘®的SPE光盘支架结合而成。该装置在实验室的一个装有防污漆的罐中进行了20多天的测试,并在收集的提取物中检测了伊加洛尔1051、SeaNine 211和迪乌隆的存在。数据显示,与暴露当天移除相比,将圆盘留在水中并没有显著降低回收率,这使其成为长期分析此类化合物的好技术。

The development of a solid phase extraction (SPE) system for environmental monitoring
This presentation describes the development of an automated solid phase extraction (SPE) device, developed from a 50 port extraction unit (Aqualab) coupled with an SPE disc holder containing a C18 speedisk®. The device has been tested in the laboratory over 20 days in a tank spiked with antifouling paints and the extracts collected tested for the presence of Irgarol 1051, SeaNine 211 and diuron. The data show no significant reduction in recovery when leaving discs in the water, compared to removing on the day of exposure, making this a good technique for analysing such compounds over long periods of time.
