Abstract

A method was developed for the detection of seven microcystins (microcystin-LR, RR, YR, LA, LY, LW and LF) in surface water using automatic solid-phase extraction (A-SPE) coupled with ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The automated solid-phase extraction system was used to extract microcystins (MCs) from water samples. UPLC-MS/MS was used to determine MCs concentrations in just 5 min. Method detection limits were from 0.3 to 0.9 ng/L, microcystin recoveries ranged from 83.8% to 114%, and the relative standard deviation (RSD) varied from 5.6% to 12.5%. This analytical approach was found to be simple, highly sensitive, accurate, which required little manual operation. Additionally, to validate this analytical method, A-SPE+UPLC-MS/MS was applied to characterize the concentration of MCs in Taihu Lake, Wuxi, China.
