Title: Planar flow-by electrode capacitive electrospray ion source

Abstract

An electrospray ion source includes a chamber including a channel region therein, the channel including at least one inlet for directing a solution into the channel and at least a first and a second outlet for transmitting the solution or derivatives therefrom out from channel. Structure for separating ions in the solution is provided from separating the solution into at least a first and a second flow stream portion. The first flow stream portion is enriched in negative ions and the second flow stream portion is enriched in positive ions. The first flow stream portion is adapted to exit the chamber through the first outlet while the second flow stream portion is adapted to exit the chamber through the second outlet. A method of charge separation can include the step of simultaneously providing at least two gas phase ion stream portions having opposite polarity.
