Nuclear Magnetic Resonance (NMR)
Salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms, the effluent from which can pollute rivers, lakes and oceans. German and Chilean scientists have used fluorescence measurements, high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy to answer this question.
Lewis E. Kay is to receive a 2017 Canada Gairdner Award for his contributions to the field of biomolecular NMR spectroscopy.
Magritek launch the Spinsolve ULTRA Benchtop NMR system for measuring sub-millimolar components of neat mixtures in under 10 minutes.
numares AG and Oxford University are collaborating to develop an nuclear magnetic resonance (NMR)-based in vitro diagnostic (IVD) test to improve therapeutic decision making for patients with multiple sclerosis (MS). This is based on research conducted at Oxford to differentiate MS patients by metabolic biomarkers using NMR spectra. numares will provide its Magnetic Group Signaling® (...
NMR spectroscopy has shown a molecule self-assembling into different forms passing from solution state to solid state and back again.
A superconducting insert coil made from a copper-oxide-based ceramic, YBCO, has raised the magnetic field achievable to 25 Tesla.
New method allows hyperpolarised xenon gas, to be dissolved into minute samples of substances without disrupting their molecular order during NMR spectroscopy.
Magritek have released new solutions that enable straightforward reaction monitoring on the Spinsolve benchtop NMR spectrometer
The protein α-synuclein plays an important role in Parkinson’s and other neurodegenerative diseases. Although a considerable amount is known about the structure of the protein within the Parkinson’s-typical amyloid deposits, nothing was known about its original state in the healthy cell up to now. High-resolution nuclear magnetic resonance and electron paramagnetic resonance spectroscopy have...
Searching for the precise, complexly folded three-dimensional structure of a protein can be a long, intensive process with uncertain direction. A technique based on nuclear magnetic resonance spectroscopy offers a solution.
Oxford Instruments and Green Imaging Technologies have introduced the GeoSpec2+ NMR core analyser.
Bruker has announced five orders for ultra-high field (UHF) nuclear magnetic resonance (NMR) spectroscopy systems from Europe and Brazil in recent months. These UHF systems have been funded for cutting-edge NMR research in structural biology, intrinsically disordered proteins (IDPs), membrane proteins, macro-molecular complexes and interactions, cell biology, disease research, as well as in...
Deutero have introduced a simple glass funnel suitable for 5-mm NMR tubes, and applicable for filling powder.

Tony Davies and Mohan Cashyap are concerned about your NMR data. When an article starts “On 10 October 2014 the impossible happened”, you will want to take note! Following the withdrawal of Agilent from the NMR business, Tony and Mohan consider three solutions to ensuring your NMR data is available now and into the future. If you have an NMR of any make, you will want to read this. Do remember...
“Rheo-nuclear magnetic resonance spectroscopy: a versatile toolbox to investigate rheological phenomena in complex fluids” is Claudia Schmidt’s topic. Rheology is an important science, and NMR has a number of uses within it. However, challenges remain for the simultaneous measurement of rheological and NMR parameters.
Many analytical methods have been used to control the quality, authenticity and origin of fresh fruit. NMR methodologies yield a comprehensive metabolic profile, provide direct structural information regarding individual metabolites in the mixture and also give information regarding the water state in the tissue. This is useful in discriminating various fruits varieties, in investigating...
Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful analytical tools used to probe details of molecular structure and dynamics. It requires very high magnetic fields and, hence, generally uses extremely large, powerful magnets. The advent of small, powerful magnets has allowed much less expensive low resolution NMR instrumentation to be designed, making it feasible to...
1H NMR spectra are usually interpreted by hand, which is very time consuming, and can become a process bottleneck in fields such as high-throughput NMR. Greater automation of the spectral analysis process has become essential if NMR is to be of value as a high-throughput analytical method in the future.
Dirk Lachenmeier, Marina Gary, Yulia Monakhova, Thomas Kuballa and Gerd Mildau describe “Rapid NMR screening of total aldehydes to detect oxidative rancidity in vegetable oils and decorative cosmetics”. Lipid oxidation produces rancid products, which are both unpleasant and potentially toxic. The authors describe the use of NMR to screen food and cosmetic products. Whilst, vegetable oils were...
