New high-throughput material–exploration system based on combinatorial chemistry and electrostatic atomization

As a tool to facilitate future material explorations, our group has developed a new combinatorial system for the highthroughput preparation of compounds made up of more than three components. The system works in two steps: the atomization of a liquid by a high electric field followed by deposition to a grounded substrate. The combinatorial system based on this method has plural syringe pumps. The each starting materials are fed through the syringe pumps into a manifold, thoroughly mixed as they pass through the manifold, and atomized from the tip of a stainless steel nozzle onto a grounded substrate.
