Laboratory Fluids Applications

  • 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 diffusion characteristics, so a measurement that collects both T2 and diffusion data should in principle be able to separate the fluid types. GIT Systems software, together with a pfg accessory on a GeoSpec2 NMR instrument, enables such measurements to be done. The result is a two-dimensional data map illustrating the relative proportions of the different fluid types in the sample.

  • 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).
