NMR sample Applications

  • Benchtop NMR Spectroscopy on liquid food samples

    Quality control is a constant challenge in food science and technology. High resolution proton NMR spectroscopy has been extensively used to characterize liquid foodstuffs, but due to the high cost of large superconducting NMR systems these methods have largely been limited to research labs. The Spinsolve benchtop NMR spectrometer can be used to analyse commercial liquid food samples. It is worth noting that NMR can measure samples that are cloudy, coloured or bubbly, and does not require the traditional sample...

  • NMR Spectrometer solutions for the reaction monitoring sector

    NMR reaction monitoring is an excellent technique for determining reaction kinetics as well as reaction end points. The measurements are quantitative with only minimal calibration. The signal has a linear response to concentration and it is generally not sensitive to the matrix. The measurement is of the complete sample and is non-destructive. The Spinsolve high-resolution benchtop NMR spectrometer can be installed directly in the fume hood of a chemistry lab to monitor the progress of chemical reactions...

  • Laboratory equipments for fluorine in industrial & construction waste

    Measuring Fluorine in Industrial and Construction Waste using Benchtop NMR MQC Analyser. Processing and recycling of industrial and construction waste often requires measuremetns of fluorine content in the materials. It mostly relates to monitoring potential emission of toxic fluorine gas and optimisation of the waste processing. Our benchtop NMR analyser MQC systems provide a fast, simple and accurate method of measuring fluorine in liquid and dry waste. The NMR technique does not require the use of any chemicals...

  • Laboratory instrumentation solutions for the food science industry

    Relaxometry has long been used in food science to determine the solid fat content (SFC), moisture content, etc. Not only can the NMReady perform these fundamental experiments, but, in addition, the option to measure high-resolution 1D 1H NMR acquisition can provide additional invaluable information through speciation (e.g., amount of saturated and unsaturated fats, cis/trans olefin conformations, % carbohydrates). qNMR QA/QC methods are also possible to validate product claims (e.g., carbohydrate content, alcohol...

  • Laboratory equipments for pore size distribution

    NMR can determine porosity and pore size distributions easily and quickly. Essentially, NMR signals are generated from liquids (oil or brine) when the sample is placed in a magnetic field and then excited with a brief pulse of radio frequency (RF) energy. Immediately after the pulse, an NMR signal appears and then dies away with a characteristic relaxation time or decay rate, known at T2. The amplitude of the signal immediately following the pulse is an indication of total fluid present, while theT2 of the signal...

  • Laboratory equipments for fluid typing

    GeoSpec2 instruments fitted with Pulsed Field Gradients (pfg) are able to carry out measurements dependent on the diffusion, flow, or distribution of the fluids within the core sample. One application is for fluid typing. It is possible that different fluids, such as heavy oils and partially bound water, may exhibit similar T2 values, which makes it difficult to identify which fluid is which using a standard T2 distribution. However, even if they have similar T2 values they are unlikely also to have similar...
