This review focuses on applications and challenges of multi-way calibrations in electrochemical analysis basedon the growing literature in this field. Chemometrics has scarcely been used for the analysis of electroanalyticaldata in comparison with its use for the other types of analytical data, because the challenges arising from thenature of voltammetric data including alterations in the baselines, and sample-to-sample potential shiftsrestricted the application of chemometrics in electrochemical analysis. We primarily emphasize the relevance ofthe subject to electroanalytical chemistry. We intend to introduce required information in multi-way calibrationand then we focus on the available second- and third-order algorithms, generation of second- and third-ordervoltammetric data and the pre-processing techniques to cope with challenges arising from the nature ofvoltammetric data. Finally, we present a number of works selected from the literature and the results will beconcluded.
