APPARATUS TO OBTAIN FLOW RATES IN PLASTICS VIA FIXED FREQUENCY, PULSED NMR |
摘要 |
A pulsed NMR analysis system and process comprising an air curtain (137), sample throughput system (P, L1, V1, V2) an user system controls (104) to establish digitized free induction decay curves (C), from which components functions are determined using linear or non-linear regression techniques to correlate the curve components to the target nuclei and to flow rates in plastic (M1 and FRR for polyethylene and MF for polypropylene).
