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.

“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.

Magritek has introduced the Spinsolve Phosphorus, the first 31P capable benchtop NMR spectroscopy system.


The Tony Davies column is a joint effort by Tony (A.N.) Davies, Mohan Cashyap, Bob Lancashire and Bob Hanson on “Exploring distributed, multi-server 1H NMR prediction”. This is the second part of the column’s investigation into the use of cloud-based services in the analytical arena. It describes a web page linking services from multiple sites on both sides of the Atlantic to deliver molecular structure drawing, 3D structure representation, name to structure conversion and display of data generated by linking chemical structures to 1H NMR prediction. May I reiterate Tony and Mohan’s plea for information on such cloud-based solutions, whether commercial or not. These can be sent to me ( and I will pass them on.


Mathieu Duval raises the question “Dating fossil teeth by electron paramagnetic resonance: how is that possible?”. Whilst we are all familiar with 14C dating, the use of EPR is less well known. In fact, there are less than 10 laboratories in the world able to carry out EPR dating of fossil teeth!

Tony (A.N.) Davies is getting excited by GHz NMR. These new high fields offer tantalising new areas of research but at a cost that generally requires their purchase by Government-funded centres of excellence. He argues that continued funding of such projects is essential, especially in difficult economic times.


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 nutritional properties, in monitoring the development of the fruit and in assessing the optimum harvesting time.

Peter Jenks has discovered quantitative NMR. in his article titled “NMR: is it the future for the analysis of organic molecules?”. If only it wasn’t so expensive, it might be the perfect method to certify pure organic compounds.


The Winescreener, a high-performance FT-NMR-based screening system that delivers rapid and cost-effective quantitative targeted and non-targeted statistical analyses of wine, is now available from Bruker. The system features a large number of parameters delivered within a single, completely automated, push-button analysis with minimal sample preparation. Quantification of 25 relevant components is delivered on one measurement and, in addition, both quality and safety are assessed by non-targeted screening. The transferability of the method, based on standard operation procedures, guarantees identical results across different analysis laboratories and, due to its self-learning nature, the solution will further increase its capabilities as new wine analyses are integrated on a global basis.


Benchtop NMR spectrometer that provides identical spectra to standard NMR spectrometers yet weighs only 10½ pounds and costs in the region of US$25,000. Sample volume is 20 µL and the spectrometer is controlled via a web browser. Data can be downloaded for use in any standalone software package.


NMR-based system to measure the influence of additives such as surfactants and dispersants on the particle–liquid interface of nanoparticle dispersants. It can also monitor other changes at the particle–liquid interface such as flocculation.


An affordable electron magnetic resonance system, occupying minimal bench space, which does not require large magnets or cooling systems. Designed for the academic market, it will be offered with a curriculum package for teaching professionals to bring the technique back into laboratories with a modular programme backed with online and written documentation.


A new software tool that provides routine NMR users with seamless support in their daily workflow of spectral interpretation. Assigning the NMR signals to structural characteristics, the software conducts a structural consistency assessment and provides spectral analysis. These results are collected in compact reports to enable easy transfer of information.

Tony (A.N.) Davies is after your advice in his latest column “Your committee needs you!”. The IUPAC Subcommittee on Electronic Data Standards is keen to learn about areas where you would like to see improvements in moving your data between your analytical instruments and data analysis and reporting packages.

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 measure commercially important characteristics of dispersion behaviour and performance, including the wetted surface area of particulate suspensions and emulsion droplet size. An important additional practical application is the ability to determine competitive adsorption and/or displacement of polymers and surfactants at interfaces. This article presents a brief overview of these new approaches together with an example of each measurement.

Chemists at the Karlsruhe Institute of Technology (KIT) and the Technische Universität München (TUM) in Germany have introduced an improvement on nuclear magnetic resonance (NMR) measurements for identifying chemical compounds.
