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 to collaborate on development of NMR-based Multiple Sclerosis diagnostic test
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® (MGS®) technology to Oxford to advance research toward the creation of a non-invasive diagnostic test.
Chemists from the University of Konstanz have used electron paramagnetic resonance spectroscopy to prove what happens when selective mutations occur to alpha-synuclein protein.
The 2017 Pittsburgh Spectroscopy Award has been made to Edward I. Solomon.
NMR spectroscopy has shown a molecule self-assembling into different forms passing from solution state to solid state and back again.
Tony Davies and Steven Brown explore the solid-state nuclear magnetic resonance spectroscopy facilities at the University of Warwick, UK.
International standards need to keep pace with the innovation in analytical equipment and practices. For example, many of the advances in nuclear magnetic resonance (NMR) spectroscopy reported in this journal in recent years have yet to find themselves mirrored by updates in the respective Recommendations of the International Union of Pure and Applied Chemistry (IUPAC), nor in the many and varied proprietary recommended reporting formats of the different peer-reviewed primary scientific journals. Not that every innovation needs to be “standardised”: with the speed of many developments it is important to find the right balance between reacting to real movements in a field and enshrining a short-lived fad in a IUPAC Recommendation.
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 helped to visualise the protein in healthy cells.
Fake or low-quality medicines and food supplements are a continuing global problem in developing nations, and indeed the developed world is not immune. A low-cost, portable prototype using nuclear quadrupole resonance spectroscopy can detect tainted medicines and food supplements.
This product focus is on Molecular Spectroscopy.
Oxford Instruments and Green Imaging Technologies have introduced the GeoSpec2+
Deutero have introduced a simple glass funnel suitable for 5-mm NMR tubes
Enhanced version of the FoodScreener for Wine Profiling that provides analysis of relevant regions in France, Italy and Spain. It also determines further authenticity parameters such as grape variety, vintage year and possible water addition. The system has been extensively validated and offers a rapid and fully automated tool to check wine quality and authenticity.
Software that enables the adjustment of experimental parameters based on real-time data during the analysis of chemical processes by NMR spectroscopy. Experts and non-experts can set up, monitor and adjust key experimental parameters. The software provides a complete workflow from data acquisition to project report with the ability to export data in multiple formats for additional processing.
FoodScreener Module for Honey
The most recent module of the FoodScreener product line allows the simultaneous identification and quantification of many honey characteristics, including sugar, acid and amino acid content as well as fraudulent addition of different types of syrup or other sugar solutions. The database developed for the module contains thousands of samples from around the world.
NMR spectrometer with high accuracy RF circuitry using digital high frequency technology. Is 43% smaller than previous models and performance features critical to NMR data collection have been improved by several orders of magnitude. A complete set of high-performance NMR probes are available for it, including a new high-sensitivity liquid-nitrogen probe capable of variable temperature experiments from –40°C to 150°C.
Spinsolve Reaction Monitoring
The Spinsolve benchtop NMR systems are seeing growth for on-line reaction monitoring, where reactants may be pumped continuously from the reactor to the NMR spectrometer and back again to provide reaction kinetics: determine reaction end points, identify intermediates and products.link.spectroscopyeurope.co.uk/27-02-082
Rheo-nuclear magnetic resonance spectroscopy: a versatile toolbox to investigate rheological phenomena in complex fluids
“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.
