About
NMR spectroscopy is a workhorse technique for material characterization. The availability of low-field NMR spectrometers enables a low-cost and high-accuracy route to high quality NMR spectroscopic analysis of complex systems such as polymer mixtures and composites. As many factors play a role in the ability of low-field NMR to characterize polymer systems, understanding tailorable instrumental factors for designing appropriate experimental methods becomes crucial.

This webinar will provide accounts of the application of low field NMR spectroscopy to the analysis of polymeric systems and discuss the impact of instrumental parameters, spectral quality, and quantitative analysis in comparison with high-field (400 MHz) spectroscopy results.

The second section of the webinar will discuss several applications of benchtop TD-NMR and spectroscopy for polymer testing and analysis in R&D and QA/QC settings. Easily performed techniques that leverage powerful hardware capabilities such as gradients and variable temperature will be highlighted.

By attending this webinar, you will discover:

1) How NMR accelerates polymer R&D and improves manufacturing quality control
2) The importance of small molecule detection in macromolecular systems
3) The influence of polymer sample properties
4) How to choose the optimum NMR instrumental parameters

Dr. Bryan S. Beckingham
Assistant Professor, Auburn University
Dr. Bryan S. Beckingham received his B.S in Chemical Engineering from Clarkson University in 2007, his Ph.D. degree in Chemical and Materials Engineering from Princeton University in 2013 and was a Materials Postdoctoral Fellow at Lawrence Berkeley National Laboratory as a member of the Material Science Division and the Joint Center for Artificial Photosynthesis prior to joining Auburn University as an assistant professor in 2016.

Dr. Beckingham is a recipient of a US Dept of Energy Early Career Award and is among the Industrial Engineering & Chemistry Research’s 2021 Class of Influential Researchers. His research group focuses on leveraging synthetic polymer chemistry and materials characterization to inform the design of novel polymer materials for target applications, with particular emphasis on polymer membranes, hierarchically structured matter and additive manufacturing polymer functional polymer systems.

Marcel Lachenmann
Senior Applications Scientist, Oxford Instruments
Marcel Lachenmann has many years of NMR and computational experience in academic laboratories and the scientific instrumentation industry. His undergraduate studies in chemistry at Johns Hopkins were followed by graduate work at Harvard, where he examined the structure and physical properties of zinc fingers by NMR. After years of experience in high field NMR, Marcel now focuses exclusively on TD and FT Benchtop NMR applications at Oxford Instruments’ main US office near Boston, Massachusetts.
