Particle characterisation

Handling, processability and performance of a material are dictated by its bulk physical properties. At LGC, we believe that characterisation and accurate measurement of crucial material attributes are an essential part of product development.


Whatever your phase of product development, we offer state-of-the-art measurements services in:

  • Optical Microscopy and Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray (EDX)
  • Particle sizing (Malvern and Sympatec: Wet and Dry methods)
  • Particle shape by image analysis (QICPIC)
  • Specific Surface Area by gas adsorption
  • Specific Surface Energy analysis by IGC
  • Density (bulk and tapped)
  • Sieve testing
  • Moisture content analysis
  • Tablet hardness, friability and disintegration assessments


We can develop, validate and transfer methods for quality control, in-process or release testing of physical properties for:

  • Drug substance
  • Drug product
  • Excipients
  • Raw materials

We also have experience in reverse engineering oral and inhaled formulations of pharmaceutical products.
