Chemometrics can be defined as the science of extracting information from chemical systems by mathematical modeling of the data obtained as a result of experimentation procedures. It can be divided into three main areas: calibration, experimental design- optimization and classification.In this talk, the fundamentals of the areas of chemometrics will be briefly presented. Then, several applications of chemometric tools for enhancing the potentiality of analytical methodologies developed in our laboratory concerning the separation field will be explored. Firstly, experimental design for optimization of several responses and factors, which has shown to be a useful way to reach optimal conditions by doing a reduced number of experiments, will be presented. Then, classification of wines using second-order capillary electrophoresis-UV-Vis detection will be discussed. Finally, several second- and third-order calibration applications with capillary electrophoretic/chromatographic data applied to quantitate target compounds in complex samples presenting highly overlapped peaks will be analyzed.
