Multivariate Curve Resolution

Course Description

Multivariate Curve Resolution (MCR), also known as Self-Modeling Mixture Analysis (SMMA), is a powerful class of semi-quantitative methods used to elucidate the composition of a multivariate set of data taken on mixtures. Unlike standard quantification methods, MCR attempts to determine the composition of the mixtures without, or with incomplete prior knowledge of the components of the system or their response in the variables (i.e. "pure-component spectra"). This course will discuss the relationship of MCR to Classical Least Squares (CLS) and Principal Component Analysis (PCA) and discuss various MCR methods. Central to this course's objectives are an understanding of the challenges in MCR and how the different MCR approaches can be applied depending on the information that is known about the system under study. The course includes hands-on computer time for participants to work example problems using PLS_Toolbox.

Prerequisites

MATLAB for Chemometricians and Chemometrics II--Regression and PLS or equivalent experience.
