Spectroelectrochemistry: shedding light on the unknown

Spectroelectrochemistry is a combination of spectroscopy and electrochemistry. This hybrid technology possesses the advantages of each technique and can record an optical and electrochemical signal simultaneously.

Spectroelectrochemistry allows researchers to collect molecular, kinetic, and thermodynamic information from reactants, intermediates, and any products involved in electron transfer process. It’s therefore possible to perform spectroelectrochemical studies on a broad range of molecules and different processes including biological complexes, polymerisation reactions, and more.

Traditionally, the configuration for spectroelectrochemical analysis consists of two instruments: one spectroscopic instrument and one for electrochemical analysis. Both instruments are connected independently to the same spectroelectrochemical cell and are usually not synchronised. Each instrument is also controlled by a different software, so two programs are needed to interpret each signal and then a further external software is needed to process and analyse the data obtained. Additionally, because synchronisation isn’t guaranteed, tests with this configuration are slow, complex, and costly.

Metrohm DropSens created something that did not exist before - a revolution in spectroelectrochemistry; the SPELEC line of instruments are fully integrated, synchronised solutions that offer more versatility to researchers. The devices include all components needed to work with spectroelectrochemical techniques in a simple, single system.
