Petrochemical Application of Low Field Benchtop NMR: Characterization of Polyols and Epoxy Resins

Near-Infrared Spectroscopy Application Note NIR–6 Near-infrared analysis of polyols This Application Note describes a fast, nondestructive, and reliable NIRS method for the determination of the hydroxyl number in polyols. Results are available in real-time, for which reason NIRS is highly…

APPLICATION NOTE Authors: Katherine Paulsen and Daniel Frasco, Thermo Fisher Scientific, Madison, WI Key words NMR, polymer, copolymer, number average molecular weight, compositional analysis Abstract Polymer molecular weight determination and copolymer compositional analysis involve the integration of the resonance signals…

Metrohm White Paper Lean manufacturing of polyurethane, assisted by near-infrared (NIR) and Raman spectroscopy Alexander Kadenkin Chemical manufacturing such as polyurethane production is characterized by a cost intensive production process combined with a negative ecological impact. These adverse effects can…
