Abstract:
1. An apparatus for performing multi-step electrochemical reactions, the apparatus comprising: one or more reaction vessels each coupled to an electronic sensor for monitoring products in the one or more reaction vessels, the electronic sensor generating an output signal related to a concentration or presence of a product, the output signal depending on a reference voltage; a fluidics system for sequentially delivering a plurality of electrolytes to the one or more reaction vessels one at a time, the fluidics system including a plurality of electrolyte reservoirs in fluidic communication through a valve block to a common passage, the common passage in fluidic communication between the valve block and the one or more reaction vessels, a wash solution reservoir in fluidic communication with the common passage via a branch passage connected with the common passage at a junction between the valve block and the one or more reaction vessels; and a reference electrode in contact with a wash solution within the branch passage, the reference electrode being in electrical communication with the one or more reaction vessels through fluid extending from the branch passage and through the common passage and providing the reference voltage to each electronic sensor without the reference electrode contacting any of the plurality of electrolytes.
