ABSTRACT:
A pulsed NMR analysis system and process comprising an on-line system to extract a sample and establish digitized free induction decay curves (C), from which curve components functions are determined using regression techniques to correlate the curve components to the target nuclei, crystalline or amorphous, and to other material characteristics, such as flow rates in plastic (MI and FRR for polyethylene and MF for polypropylene). The invention makes use of Principal Component Analysis (PCA) for deriving an orthogonal set of explanatory parameters and therefrom a set of vectors wherein collinearity is eliminated by Eigenvalue analysis.
