Abstract
An electrochemical detector cell includes a first block having a planar first working surface, and a first working electrode embedded in the first block member. The first working electrode includes analyte contacting surface disposed co-planarly with the first working surface. A second block member has the second working surface placeable in an opposed, adjacent relation to the first working surface, and has an inlet port disposed an opposed, adjacent relation to the analyte contacting surface of the first working electrode. The second block also includes a coupling means for permitting an analyte delivery tube to be coupled to the second block member to position an end of the analyte delivery tube adjacent to the inlet port. A generally circular circumferential channel for collecting analyte is disposed radially outwardly of the first working electrode. An outlet is disposed at the channel for conducting analyte away from the channel. A reference electrode is disposed in a diametrically opposed relation to the outlet, and a ring-like gasket is placeable between the first and second block members for maintaining the first and second working surfaces in a predetermined spaced relation. The gasket includes a radially inner diameter disposed radially outwardly of the channel. The inlet port, channel, first working electrode, first working surface, second working surface, gasket and outlet port are configured to create a generally centrosymmetric thin layer radial flow path for the analyte across the working electrode, and between the first and second working surfaces, into the channel and out of the outlet port.
