TY - JOUR A1 - Zientek, Nicolai A1 - Meyer, Klas A1 - Kern, Simon A1 - Maiwald, Michael T1 - Quantitative online NMR spectroscopy in a nutshell T2 - Chemie Ingenieur Technik N2 - Online NMR spectroscopy is an excellent tool to study complex reacting multicomponent mixtures and gain process insight and understanding. For online studies under process conditions, flow NMR probes can be used in a wide range of temperature and pressure. This paper compiles the most important aspects towards quantitative process NMR spectroscopy in complex multicomponent mixtures and provides examples. After NMR spectroscopy is introduced as an online method and for technical samples without sample preparation in deuterated solvents, influences of the residence time distribution, pre-magnetization, and cell design are discussed. NMR acquisition and processing parameters as well as data preparation methods are presented and the most practical data analysis strategies are introduced. PB - Wiley-VCH Verlag GmbH & Co.
