NMR Spectroscopy Applications

  • Laboratory equipments for well log calibration

    Down-hole NMR tools are routinely run during the oil and gas exploration process and provide valuable information to the reservoir engineers. The tools measure T2 distribution as a function of depth. T2 can be directly related to pore size and with the correct T2 cut-off can allow the determination of bound fluid versus free fluid in the reserve. These values can then be used to estimate recoverable reserves.

  • Laboratory equipments for food authenticity screening: edible oil adulteration

    Using Benchtop NMR to detect Olive Oil Adulteration with Hazelnut Oil: Adulteration of Extra Virgin Olive oil with lower cost and poorer quality oils is a known problem. This is a challenge for other techniques, such as FTIR, as the olive oil and hazelnut oil spectra are extremely similar. However, their NMR spectra show sufficient differences to allow better levels of detection of the adulterant.

  • Laboratory equipments for fat oil & grease FOG in waste water

    Measurement of Fats, Oils and Grease (FOG) in waste water is a crucial parameter in water quality control and environmental monitoring performed by water suppliers’ laboratories and environmental authorities; the contamination builds up in the sewerage system and will eventually lead to blockages. Typically the waste water is analysed by first passing a large volume through a filter then selectively determining the grease build-up on the dried filter by an analytical method.

  • Laboratory equipments for fluorine content in alumina

    Measuring Fluorine Content in Mineral Powders and Ores using the MQC Benchtop NMR Analyser. Fluorine-containing minerals such as fluorspar (fluorite) and cryolite are natural sources of fluorine that are widely used in the chemical industry (manufacturing of hydrofluoric acid and fluoropolymers for example), metallurgy (steel and alumina processing), the pharmaceutical industry and others. The fluorine content often has a significant effect on the processing of such mineral powders. Therefore, it is essential to know the fluorine concentration in order to ensure optimal processing and monitor/control emissions of toxic fluorine gases, for example in the Hall–Héroult process used to produce aluminium.

  • Laboratory equipments for pore throat distribution & wettability

    Having obtained a Pc curve, pore throat distributions can now be calculated using the Washburn equations. The imbibition and secondary drainage curves generated by the NMR Pc measurement also allow USBM wettability to be predicted. Both of these calculations are integrated into the software, and follow as a natural consequence of the NMR Pc data. A further added advantage is that the NMR measurement is non-destructive and can use reservoir fluids and reservoir wettability.

  • Laboratory equipments for analysis of unsaturated fat in seed oils

    Triglycerides are the main constituents of vegetable oil (typically more unsaturated) and animal fats (typically more saturated). They are formed by combining glycerol with three molecules of fatty acid to form ester bonds. The fatty acid composition of oils is commercially important, for example, high oleic acid content found in olive oils, has been implicated in a reduced risk of heart disease. Linoleic acid found in sunflower oils, is an essential nutritional fatty acid. High levels of these fatty acids can increase the commercial value of an oil, whereas excessive amount of linolenic acid can decrease the value since it is more susceptible to oxidation and problems with rancidity.

  • 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 and complicated sample preparation.

  • 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 gives valuable information about the physical environment of the fluid (ie. size of pore where the fluid is located).

  • Laboratory equipments for Solid Fat Content (SFC)

    Measuring Solid Fat Content (SFC) using the Benchtop NMR MQC Analyser. The measurement of solid fat content (SFC) within the baking, confectionary and margarine industries is crucial as fats are a key component in many processed foodstuffs produced within these industries. Fats are complex ingredients which play a key role in nutrition and consumer appeal of products. Measurement of solid fat content (SFC) is the industry standard approach to understanding the melting behaviour of edible oils and fats. The reason this is so important is that the melting profile of fats is one of the parameters which must be carefully controlled to ensure consistent products.

  • Laboratory equipments for fatty acid composition of triglycerides

    The fatty acid composition of oils and fats is important for health (for example, high levels of polyunsaturated fats and omega-3 oils are generally considered to be good for health; foods with a high level of saturated fat content are considered unhealthy).

  • Laboratory equipments for core analysis

    Until recently, a high level of expertise and knowledge of the principles and practice of NMR has been needed to perform NMR core analysis. Consequently, NMR core analysis has been confined to a relatively small group of Special Core Analysis Laboratories. Now, a partnership between Oxford Instruments and Green Imaging Technologies brings new hardware and software, with improved performance, to enable any core analysis laboratory to generate the petrophysics values that the industry needs without the requirement that every dataset be analysed by an NMR expert.
