Analysis Services

We provide four main types of analytical service:



Particle size and shape analysis

Analysis of sediments, soils, dust, sludge, construction materials, industrial products, suspended sediment in water and effluents by:


  • Laser diffraction
  • Dry and wet sieving
  • Pipette analysis
  • Image analysis (digital photography or optical microscopy)
  • Scanning electron microscopy
  • Direct measurement
  • We are members of the NMBAQC Scheme, and validated by the MMO for particle size analysis of marine sediments



Chemical and mineralogical analysis of sediments and soils

  • Chemical analysis by ICP-OES and ICP-MS
  • Mineralogical analysis by XRD
  • Optical and scanning electron microscope examination
  • Quantitative colour analysis
  • Loss on ignition and acid weight loss determination
  • Particle shape and surface texture analysis


Processing of topographic and bathymetric data

  • RTK GPS surveys
  • LiDAR surveys (airborne and terrestrial)
  • Bathymetric profile data
  • 3D swath bathymetric data
  • Analysis of historical maps and aerial photographs
  • Data synthesis using GIS
  • Volumetric change analysis of digital elevation models


Processing and analysis of environmental data

  • Wind, precipitation and temperature data
  • Tide gauge data
  • Wave data
