    Determination of mercury in soil, bottom sediments, and geological materials

    INTRODUCTION

    Analysis of soils and bottom sediments for mercury content is one of the most common analyses in the monitoring of environmental pollution. Background mercury concentrations in these objects are 10–100 μg/kg and in the polluted areas they exceed 10,000 μg/kg.

  • Electrical Based Tomography Systems for Multiphase Flow

    Multiphase flows are complex and unpredictable however they have a significant bearing on the safety, costs and revenues of many processes – particularly in oil and gas, but also in aerospace, chemicals and other sectors.

  • Electrical Based Tomography Systems for Crystallisation/Precipitation

    Crystallisation is a key reaction in pharmaceutical and other process sectors. The combination of two ionic species in solution to form a solid frequently produces a strong change in electrical properties which can be tracked using ITS electrical resistance tomography sensors. Sensor arrays are produced on two different formats:

  • Geotechnical Applications

    Pore pressure variability and control is one of the most significant aspects of Geotechnical Engineering practice related to slope stability, underground openings, foundation of heavy structures, and water retention facilities. Pore pressure effects are most often controlled by natural small-scale hydrogeologic details. Characterization and management of pore pressures requires closely-arrayed repeated measurements to determine the effects of these details for design of appropriate mitigation measures, for performance monitoring and control of the selected mitigation measure. Since the late 1970’s the Westbay System has been used on some of the largest landslide studies in the world.

  • Electrical Based Tomography Systems for Slurry Flow

    Slurry transportation is required in a diverse range of sectors, from food to minerals processing; and oil sands processing to nuclear waste management. As a process it requires significant levels of energy and the abrasive nature of materials used can lead to ongoing issues of pipeline erosion.
