title: Forensic investigation of gentamicin sulfates by anion-exchange ion chromatography with pulsed electrochemical detection.
abstract: Many methods exist for the separation of gentamicin C complex components, C1, C1a, C2 and C2a. In an investigation of possible counterfeit suppliers of gentamicin sulfate, a new method utilized high-pH anion-exchange separation on a carbohydrate column, with pulsed electrochemical detection on a gold electrode. Component ratios and the presence and/or absence of additional peaks were used to link or dissociate forensic samples.
