Abstract:
Multivariate Curve Resolution (MCR) is a group of techniques which intend the recovery of the pure response profiles (spectra, pH profiles, time profiles, elution profiles,....) of the chemical constituents or species of an unresolved mixture obtained in chemical processes when no prior information is available about the nature and composition of these mixtures. MCR algorithms have seen a broad range of applications in the literature. In particular, spectral monitoring of processes such as chemical kinetics, chemical equilibrium, chromatography and industrial process analysis is well suited for analysis using MCR techniques. Spectroscopic image analysis is another area where MCR techniques have been found to be very useful. Specific applications that have been reported include time-of-flight secondary ion mass spectrometry, (ToF-SIMS) imaging, IR imaging of plant tissue, Raman imaging of an emulsion, Raman and NIR imaging of pharmaceutical tablets. The localization and distribution of pigments within individual cyanobacterial cells using confocal fluorescence imaging has recently been demonstrated.

Brief CV:
Anna de Juan has been an associate professor at the Department of Analytical Chemistry at the University of Barcelona since 2003, teaching chemometrics at undergraduate and graduate levels. She holds a degree and Ph.D. in Chemistry from the University of Barcelona and her expertise is in multivariate curve resolution (MCR) methods: theoretical development and application to bioanalytical and analytical problems. Since 2002 she has been a member of the Editorial Advisory Board of Chemometrics and Intelligent Laboratory Systems and since 2006 of Analytica Chimica Acta. In 2004, she received the 4th Chemometrics Elsevier Award
