The particle properties of a powder — such as particle size, shape, surface area and porosity — can affect both the performance and process ability of a drug due to their effect on dissolution, stability, handleability and flow properties, impacting critical attributes such as tablet uniformity or suspension stability. Micromeritics is the study of particles and their properties, and pertains to powders, suspensions and emulsions.

We offer micromeritics capabilities, including fit-for-purpose method development and routine analytical services for:

  • Particle size analysis
    • Laser light scattering (Malvern Mastersizer 2000 and 3000 instruments, equipped for dry and wet analysis)
    • Sonic sieving
    • Dynamic light scattering
    • Light obscuration (AccuSizer particle counter and sizer)
    • Microscopy and image analysis
    • Particle morphology and size range
    • Scanning electron microscopy (SEM)
  • Surface area analysis by BET technique
    • Micromeritics Gemini V and VII models
    • Micromeritics TriStar (N2 and Kr)
  • Bulk and tapped density
  • Density
