UV-Vis absorption SEC is a recent technique that is continuously evolving. However, many advantages have been observed over other techniques. The most outstanding advantages are:
* It generates a large amount of information about the systems.
* Generally, solvents are not a problem when carrying out these kinds of measurements.
* The wavelength selection generates specificity in the measurement of each species.
* Currently, there are commercial devices that allow carrying out a large number of experiments with high reproducibility.
* The kinetics of the reactions can be studied.
* It is used to determine a large number of electrochemical and optical parameters.
* Trilinear signals are obtained.
* Small amounts of sample can be analyzed.
* Faradaic current can be separated from non-faradaic current in an electrode process.
* It is more specific than electrochemistry.
* Quantitative information can be obtained.
UV-Vis absorption SEC has been used mainly in different research fields such as:
* Sensor development.
* Reaction mechanisms.
* Diffusion and adsorption processes.
* Characterization of compounds.
* Study of biological interest substances.
* Study of optical and electrical materials properties.
* Study of liquid/liquid interfaces.
* Study and synthesis of nanomaterials.
* Evaluation of reaction parameters in which electron transfer occurs.
