A look at the market for spectroelectrochemistry and some of the products and solutions available
S
pectroelectrochemistry (SEC) is a set of multi-response
analytical techniques in which complementary chemical information can be obtained in a single experiment. It is able to provide a whole vision of the phenomena that take place in the electrode process. The techniques date back
to the 1960s, with the first recorded spectroelectrochemical experiment carried out by Theodore Kuwana and a team of researchers in 1964. The team had begun to work with transparent electrodes to study a process that involved measuring charge and absorbance simultaneously when a beam of light passes through an electrode. The experiment led to the development of transparent electrodes to carry out combinations of optical and electrochemical experiments.
32 Electro Optics May 2022 Spectroelectrochemistry is
largely based on electrochemistry and spectroscopy techniques. In more recent years, the technique has grown in popularity, thanks to the increase in its versatility, as it can perform several electrochemical techniques in different spectral regions depending on the purpose of the study and required information. Some of the technique’s key
advantages include the ability to obtain simultaneous information using different techniques in a single experiment, as previously mentioned. This can increase the selectivity and the sensitivity. It also allows for both qualitative and quantitative information to be obtained. Spectroelectrochemistry also enables the possibility of working with a small sample and saving it for future analysis. Because of the increased
versatility and various benefits, a
number of different applications and use cases have become available, including the study of reaction mechanisms, where both oxidation and reduction involved in the reaction can be observed, as well as the generation of reaction intermediates. It is also used in the characterisation of organic and inorganic materials and the development of spectroelectrochemical sensors. Different processes and molecules in biotechnology, biochemistry or medicine can also be studied, while specific properties and characteristics of new materials in fields such as energy or nanotechnology can be determined.
Commercial
products Vendors of products in the spectroelectrochemistry market
include Agilent Technologies. Its 8700 LDIR Chemical Imaging System provides a rapid and simplified path to molecular imaging using Quantum cascade laser (QCL) coupled with rapidly scanning optics, replacing the globar based interferometer and focal plane array detectors of traditional FTIR imaging systems. Applications include compositional analysis of pharmaceutical tablets, microplastics, laminates, tissues and fibres. ALS provides researchers
with a range of products for electrochemistry and spectroelectrochemistry applications, including Ring-Disk Electrode apparatus, Faraday cage (CS-3A), Spectrometer (SEC2020) and Portable Hydrogen Generator (H2G1). The company also offers a number of spectroelectrochemical cells, Quartz Crystal Microbalances cell/Quartz crystal
