The spectroelectrochemistry experiment is based on the in-situ formation of a suitable substrate that enables the enhancement of the Raman signal of an analyte during the oxidation stage of a silver electrode. This phenomenon is known as electrochemical surface oxidation enhanced Raman scattering (EC-SOERS) and has proved to be useful in quantitative analysis using disposable screen printed electrodes. The successful combination of EC-SOERS with PARAFAC analysis allows the determination of uric acid in a relevant complex sample avoiding the use of standard addition method and without using a baseline correction, which simplifies the application of such methodology in routine analysis. 0003-2670 http://hdl.handle.net/10259/5336 10.1016/j.aca.2019.07.057 Spectroelectrochemistry Electrochemistry Raman EC-SOERS Determination of uric acid in synthetic urine by using electrochemical surface oxidation enhanced Raman scattering
