Determination of Trace Level Microcystins in Water Using Solid-phase Extraction and High Performance Liquid Chromatography / 分析化学

ABSTRACT

This paper presents a method for trace level analysis of microcystins in water using solid-phase extraction and high performance liquid chromatography.The optimized condition enabled the determination of common microcystins at levels as low as 0.02～0.05μg/L,and the liner range is from 0.1μg/L to 50 μg/L. The method has been applied to the analysis of field sample from Dianchi lake.
