In NMR, magnetic nuclei of specific isotopes are aligned by a strong external magnet and then perturbed by a radio wave.

We can detect about 50 different metabolites. Nuclear Magnetic Resonance (NMR) Spectroscopy is a powerful analytical technique that can reveal structural information about many organic and inorganic molecules. NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI). The metabolomics platform provides a broad range of metabolomics services including sample analysis, data analysis and interpretation, by HRMAS NMR. Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials. Using intact samples gives us the power to remove any contamination or damage risk of biological samples, caused by long and time consuming chemical extraction procedures, and to analyze a large number of samples in a short period of time.

En effet, les molecules observees sont exclusivement intracellulaires. La spectroscopie de RMN: Principes de base, concepts et applications de la spectroscopie de rsonance magntique nuclaire du proton et du carbone 13 en. HRMAS NMR technique is a powerful, reliable and robust technique that allows rapid spectra acquisition (10 min of acquisition per sample) from intact tissue or cell samples. La spectroscopie RMN est un moyen unique devaluer lenvironnement cellulaire in vivo. The main activity of our platform consists in characterizing the metabolic profile of different type of solid biological samples (tissue, cells) from small amounts of biological materials (2 to 15 mg) by high resolution (HR) Magic Angle Spinning (MAS, 54.7°) nuclear magnetic resonance (NMR). Appareil et procd de spectroscopie distance par RMN/RMI comprenant une bobine de codage pourvue dune chambre dchantillon, un organe fournissant des. The spectrometer has all necessary equipment to perform fully automated high-throughput investigations.We are a research team expert in metabolomics, working in a medical environment. INFAI operates a newly purchased, state-of-the-art NMR spectrometer, a Bruker Avance III 600MHz liquid-state spectrometer (see pictures below). It has experienced a tremendous development over the last decades, and keeps evolving at an amazing pace. Nuclear magnetic resonance is among the most powerful spectroscopic techniques in use today. A Method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprising the following steps: (a) excitation of long lived coherences (LLC) between.
