DigiM works on a variety of pharmaceutical applications using our unique image-based charactorization technique,

  • Compaction completeness with assessment on porosity, granularity, API re-aggregation;
  • Multi-layer coated dosage for movement of API, distribution of anti-tacking agents, change in osmolality;
  • Tablet coatings for the surface roughness, completeness of surface consolidation, distribution of lubricant. voids between coating and tablet, coating consolidation;
  • Micro-structure and drug release correlation;
  • Quantification of API crystalline;
  • Generic drug bioequivalence evaluation.
