Abstract
|
|
|
|
A new HPLC method for the analysis of cyanobacterial toxins, i.e. microcystin was developed using cyano-type prepacked cartridge while the conventional method was to utilize ODS cartridge. The cartridge was washed with 0.5 M acetic acid, then microcystins RR and LR were eluted from the cartridge with 30% acetonitrile. A better degree of quantitation was observed than with a ODS cartridge. Especially, in the case of microcystin LR a great difference in peak area was observed.
