Application of Chemometrics in Separation Science

Abstract Chemometrics aims at extracting maximum information through the application of statistics and mathematics to problems of a chemical nature. Over the years, chemometrics has become an important chemical discipline with a significant impact in analytical chemistry, including the incorporation of significant improvements in design and selection of optimal experimental procedures, calibration of analytical instrumentation, and advanced methods for analysis of chemical data. The application of chemometrics methods to separation science, mainly chromatography and capillary electrophoresis, has followed the same increasing trend as in any other field of analytical chemistry. However, reviews on the application of chemometrics in separation science have been very scarce. Therefore, in this paper, the development of chemometrics in chromatography and capillary electrophoresis will be presented with a view of the current state of the‐art and with the prospects for the future.
