| Abstract: | Summary A new method for the determination of microcystins PR and LR in cyanobacterium was developed using cyano-type prepacked cartridges. The microcystins were extracted with 10% acetic acid and the extract applied to a Baker 10 cyano cartridge. After elution from the cartridge with 0.5M acetic acid-acetonitrile (1 9) the microcystins were determined by HPLC. Better recoveries and chromatograms were observed than with ODS cartridges. |
