Original Abstract

We present a portable lock-in amplifier-based electrochemical sensing system. The basic unit (cluster) consists of four electrochemical cells (EC, each containing one pseudo-reference electrode (PRE) and one working electrode (WE). All four ECs are simultaneously interrogated, each at different frequency, with square wave pulses superposed on a sawtooth signal for cyclic voltammetry (CV) Lock-in amplification provides independent read-out of four signals, with excellent noise suppression. We expanded a single cluster system into an array of cluster using electronic switches.
