Abstract
In one embodiment, the present invention is directed to a pulsed electrochemical detection method comprising (a) flowing a liquid sample stream including at least one analyte past a working electrode in a flow-through cell; (b) applying at least three pulsed electrical potentials to the working electrode, (1) a first conditioning potential, (2) a second detection and oxidative cleaning potential, and (3) a third reductive cleaning potential, said second potential being higher than said first and third potentials and said first potential being higher than said third potential; and (c) detecting the output from said working electrode during the time period of applying said second potential.
