Flow chemiluminescent determination of catecholamines based on permanganate oxidation.

Luminous oxidation with acidic permanganate was found to be usable for chemiluminescent determination of catecholamines and other polyhydroxybenzenes at picomol levels. The sensitivity is high enough to determine catecholamines in urine. The present CL method is expected to be applicable to the post-column detection of these compounds in high-performance liquid chromatography.
