The evolution of chemometrics
In this editorial, Richard Brereton reflects on historical and future aspects of chemometrics as a discipline.
Pre-processing in vibrational spectroscopy – when, why and how
Pre-processing is nothing without scattering.
Multivariate Curve Resolution (MCR). Solving the mixture analysis problem
This article is a tutorial that focuses on the main aspects to be considered when applying Multivariate Curve Resolution to analyze multicomponent systems, particularly when the Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) algorithm is used.
