A light emitting diode based photoelectrochemical screener for distributed combinatorial materials discovery
Gates R. Winkler and Jay R. Winkler
A system that uses an array of pulsed LEDs synchronized with a two-electrode potentiostat that can measure the photoelectrochemical responses of combinatorial sample arrays deposited on conducting glass plates is developed. Compared to raster scanning methods, this LED system trades spatial resolution for a substantial reduction in scan time.
