Abstract

Recent methods employed for the analysis of algal toxins have focused on high performance liquid chromatography. However these methods suffer from poor resolution, poor efficiency, and long analysis times. This study involves the investigation of a number of toxins including nodularin, microcystin LR, YR, and RR which are cyclic peptides produced by strains of blue‐green algae. The electroseparation mode was micellar electrokinetic capillary chromatography (MECC) using a borate buffer containing sodium dodecyl sulfate (SDS) as the surgactant of choice. The method was optimized with standard toxin compounds and employed for the screening opf toxins in supercritical fluid extracts (SFE) of freeze‐thawed algal scum samples.

A micellar electrokinetic capillary chromatographic method for the separation of anthraquinone positional isomers was established. The running electrolytes used in this method were 0.03 M sodium dodecyl sulphate (SDS) in 0.03 M borate buffer (pH 9) containing 10% acetonitrile for dihydroxy-and dihyd
