Abstract
Pulsed NMR system for industrial measurements comprising sample throughout system (P, LI, V1, V2) and user system controls (104) to establish digitized free induction decay curves (C), from which Abragam, Gaussianand exponential components are determined using a Marquardt-Levenberg iteration technique, and using regression techniques to correlate the curve components to the target nuclei.
