Legion: An Instrument for High-Throughput Electrochemistry

Electrochemical arrays promise utility for acceleratedhypothesistesting and breakthrough discoveries. Herein, we report a new high-throughputelectrochemistry platform, colloquially called "Legion,"for applications in electroanalysis and electrosynthesis. Legion consistsof 96 electrochemical cells dimensioned to match common 96-well platesthat are independently controlled with a field-programmable gate array.We demonstrate the utility of Legion by measuring model electrochemicalprobes, pH-dependent electron transfers, and electrocatalytic dehalogenationreactions. We consider advantages and disadvantages of this new instrumentation,with the hope of expanding the electrochemical toolbox.
