Noise effects on band boundaries in multivariate curve resolution of three-component systems

The boundaries of the set feasible bilinear solutions for three-component systems have been estimated in presence noise, as a sequel previous report on two-component data sets. Simulations involving significant degree overlap among component profiles both matrix modes analyzed using FACPACK and recently described sensor-wise N-BANDS model. latter computes upper lower envelopes showing maximum minimum intensity at each sensor. For three more components, graphical representation extreme corresponding to signal contribution function provided by methods such MCR-BANDS do not enclose, general, full profiles. present results were obtained under non-negativity only constraint profiles, successfully compared with those noise addition procedure. A experimental system was also regarding combined effect rotational ambiguity instrumental noise.
