Magic Angle Spinning NMR Metabolomics.
Nuclear Magnetic Resonance (NMR) spectroscopy is a nondestructive, quantitative, reproducible, untargeted and unbiased method that requires no or minimal sample preparation, and is one of the leading analytical tools for metabolomics research [1-3]. The easy quantification and the no need of prior knowledge about compounds present in a sample associated with NMR are advantageous over other tech...
متن کاملMultiple-quantum magic-angle spinning and dynamic-angle spinning NMR spectroscopy of quadrupolar nuclei.
Several aspects of the Multiple-Quantum Magic-Angle Spinning (MQMAS) technique (L. Frydman and J.S. Harwood, J. Am. Chem. Soc., 117 (1995) 5367) are compared with Dynamic-Angle Spinning (DAS). Examples of MQMAS spectra are shown for I = 3/2 nuclei with CQ up to 3.6 MHz, and for 27Al (I = 5/2) with CQ up to 10 MHz. The MQMAS linewidth is largely independent of the magnitude of the homonuclear di...
متن کاملMicrocoil high-resolution magic angle spinning NMR spectroscopy.
We report the construction of a dual-channel microcoil nuclear magnetic resonance probehead allowing magic-angle spinning for mass-limited samples. With coils down to 235 mum inner diameter, this allows high-resolution solid-state NMR spectra to be obtained for amounts of materials of a few nanoliters. This is demonstrated by the carbon-13 spectrum of a tripeptide and a single silk rod, prepare...
متن کاملUltrafast high-resolution magic-angle-spinning NMR spectroscopy.
We demonstrate the acquisition of ultrafast 2D NMR spectra of semi-solid samples, with a high-resolution magic-angle-spinning setup. Using a recent double-quantum NMR pulse sequence in optimised synchronisation conditions, high-quality 2D spectra can be recorded for a sample under magic-angle spinning. An illustration is given with a semi-solid sample of banana pulp.
متن کاملEnvironmental NMR: High-resolution Magic-angle Spinning
Environmentally significant materials including soils, plant tissues, melanin pigments, and urban surface films possess swollen or swellable constituents that are not studied ideally using either solutionor solid-state NMR. Beginning in the 1970s and accelerating during the past 15 years, high-resolution (HR)-MAS techniques have been developed to study these challenging materials, yielding unpr...
