Catheter microelectrode assembly for in-vivo and in-vitro voltammetric analysis of body fluids.
An electrode assembly suitable for voltammetric analysis of very small sample volumes, in vitro or (vivo), has been constructed inside a catheter. Well-defined differential pulse current peaks have been obtained for acetaminophen, chlorpromazine and ascorbic acid at the submillimolar concentration level. Voltamperograms recorded for rhesus monkey blood in vivo and in vitro were similar.
