Abstract

This abstract demonstrates, for the first time, capacitive deionization (CDI) inside a chip measured using impedance spectroscopy [1]. CDI is a promising technique for the pre-treatment of extremely small volume protein samples (nL range) before analysis by mass spectroscopy [2]. The results included in this abstract are two-fold; (1) validation of our device and measurement method on the macro-scale and (2) proof-of-principle measurements using a microfluidic chip under flow conditions. We demonstrate desalination up to ~25%. Moreover, we show that capacitive desalination is a localized process, mainly taking place in close proximity of the electrode [3].
