Analytical chemistry assisted by multi-way calibration: A contribution to green chemistry.

A review is presented of recent multi-way calibration protocols involving three-, four- and five-way data. A brief description of the various data structures and processing models is shown, with emphasis on model selection based on the matching between the data structure and the physicochemical model assumptions. Calibration research works are then discussed, classified according to the type of measured instrumental data and model/algorithm selection. Image 1 • Recent multi-way calibration protocols are reviewed. • The relationship between data structures and chemometric models is detailed. • Second-, third- and fourth-order data generation is discussed. • Implications to green analytical chemistry are underlined.
