Accurate and Precise External Calibration Enhances the Versatility of Quantitative NMR (qNMR)

Yuzo Nishizaki et al.

Summary: This study utilized the principle of reciprocity and certified reference materials to achieve accuracy and precision in external calibration qHNMR. By optimizing nutation experiments and carefully timing the tuning and matching process, the achieved accuracy of around 1.0% demonstrates the feasibility of EC-qHNMR as a highly practical research tool.

Quantitative NMR (qNMR) for pharmaceutical analysis: The pioneering work of George Hanna at the US FDA

Birgit U. Jaki et al.

Summary: In the last two decades, qNMR has become increasingly important for the analysis of pharmaceuticals, chemicals, and natural products. George M. Hanna's pioneering work between 1984 and 2006 has connected with recent progress in low-field benchtop NMR instruments, establishing the utility of qNMR well ahead of his peers in routine quality control analyses in pharmaceutical and related operations. His work has the potential to inspire new developments in qNMR applied to small molecules of biomedical importance.
