Multifunctional systems (MFS) comprising impact modifiers, processing aids, lubricants, stablizers, and fillers are utilized throughout the PVC industry to impart greater consistency, obtain faster and easier blending cycles, reduce inventory, and minimize cross‐contamination. Qualitative and quantitative product analysis, to ensure adherence to performance specifications, is an integral part of any quality control function. Near‐Infrared (NIR) spectroscopy coupled with chemometrics techniques enables one to distinguish clearly among different MFS formulations (product identification) and to detect changes in product composition for each formulation (product qualification). Additionally, models can be developed to provide a completed compositional analysis.
