Resumen:
The discrimination power of multivariate curve resolution-alternating least squares (MCR-ALS) and parallel factor analysis (PARAFAC) are evaluated for the analysis of room-temperature fluorescence excitation emission matrices (RTF-EEM) recorded from textile fibers and their respective extracts. RTF-EEM data formats are directly recorded from non-extracted fibers with the aid of a sample holder specially designed to optimize signal-to-background ratio. We demonstrate that the combination of RTF-EEM spectroscopy to chemometric analysis provides a valuable tool for non-destructive analysis of forensic evidence.
