Electrochemical detection of the 3,5-dinitrobenzoyl derivative of digoxin by high-performance liquid chromatography.


Electrochemical detection of 3,5-dinitrobenzoyl derivatives of digoxin and its metabolites following high-performance liquid chromatography is reported. Partial resolution of derivatized digoxin and dihydrodigoxin was obtained using a Spherisorb ODS II analytical column. Both single- and dual-electrode detection were investigated and a maximum sensitivity… (More)
