Applications

Thermodynamic and Kinetic Characterization of a Hydrolysis Reaction Using the Adjustable Temperature Feature of the Fourier 80

Benchtop Nuclear Magnetic Resonance (NMR) spectrometers are versatile tools for structure elucidation and verification, reaction monitoring, and quality control. In contrast to their larger, floor standing counterparts they are an order of magnitude less expensive in acquisition, have negligible operating costs, and require only minimal laboratory infrastructure.

APPLICATION NOTE

NMR for Poloxamers/Polymers

This application note describes how Bruker’s FT-NMR benchtop spectrometer, the Fourier 80, was used to quantify the oxyethylene weight percentage in poloxamers.

Application Note

Industry/Hygiene Solutions

Hand hygiene has been at the center of the global response to the COVID-19 pandemic, with alcohol-based sanitizers playing a key role. However, several reports indicate that hand sanitizer fraud is prevalent. Rapid testing methods such as benchtop Nuclear Magnetic Resonance (NMR) spectroscopy can determine the alcohol content or percentage volume (% vol) of hand sanitizers in seconds, preventing fraud.
