AB  - A method for the determination of five microcystins (MCs) in water was 
      established using liquid chromatography (LC)-diode array detection (DAD)/ion trap 
      mass spectrometry (IT MS). The five MCs in water were enriched and purified by 
      solid phase extraction, and determined by LC-DAD/IT MS. DAD was used for both 
      qualitative and quantitative analysis, and IT MS was used for qualitative 
      analysis only. Under the optimized conditions, the detection limits of 5 MCs in 
      water were 0.1 microg/L. The average recoveries of the three spiked levels (0.2, 
      0.8 and 5 microg/L) were 52.2% - 115.2% with the relative standard deviations 
      (RSDs) of 1.2% - 10.0%. This method uses UV absorption spectrum and MS spectrum 
      in the qualitative and quantitative analysis, and can be applied in the 
      determination of various MCs in both surface water and drinking water.
