Large-volume sample stacking using the electroosmotic flow (EOF) pump (LVSEP) has been used to analyze some nonsteroidal anti-inflammatory drugs (NSAIDs) in water samples. With methanol as the run buffer solvent to suppress the EOF, sensitivity was enhanced by 80-100-fold. The sample for the analysis of real water sample was pretreated by solid-phase extraction (SPE). When the method was based on off-line SPE-LVSEP-CE, sensitivity improved by as much as 1000 times.
使用电渗流（EOF）泵的大体积样品堆积（LVSEP）已用于分析水样中的一些非甾体抗炎药（NSAIDs）。以甲醇作为运行缓冲溶剂来抑制电渗流，灵敏度提高了80至100倍。用于分析实际水样的样品通过固相萃取（SPE）进行预处理。当该方法基于离线SPE-LVSEP-CE时，灵敏度提高了多达1000倍。
