The mission of the NMR facility is to provide scientific and technical expertise in NMR spectroscopy and to provide users with open-access to a range of functional equipment. In particular, the facility carries out and interprets NMR spectra on specific problems. It can carry out detailed studies as part of scientific collaborations or service deliveries. It is also responsible for the maintenance of the spectrometers, training and assistance to users of open-access equipment.
The NMR service is open to researchers from outside the laboratory and from the private sector. The service is part of the “RMN Midi-Pyrénées” network.

NMR (Nuclear Magnetic Resonance) is a non-destructive chemical analysis technique commonly used to determine the molecular composition and purity of a sample.
It allows the identification of molecules, the determination of their structure and the study of some of their physical properties in solution or in the solid state (change of conformation, phase, solubility, size…).
This facility offers a wide range of services that can be integrated into your R&D projects in a wide variety of scientific fields (materials, organic chemistry, catalysis, natural products, etc.). Today, we carry out NMR measurements for more than twenty public or industrial laboratories.
The NMR facility can offer you solutions ranging from simple access to NMR spectrometers for routine controls to the complete handling of your samples by our engineers (preparation of samples for analysis, performance of measurements, interpretation of results, drafting of an analysis report, etc.). Any service will be subject to a detailed quote that we will draw up according to your needs.
