Exploiting the high oxidation potential of carisoprodol on a boron-doped diamond electrode: an improved method for its simultaneous determination with acetaminophen and caffeine.

A boron-doped diamond electrode (BDDE) was employed for the first time in the development of a voltammetric method for the simultaneous determination of acetaminophen (ACT), caffeine (CAF) and carisoprodol (CAR). CAR presents a high oxidation potential (2.0 V) and this electrode is suitable for this purpose due to its wide electrochemical potential window.
