Particle Size Testing for Inhalation Drug Products

Why Particle Size Matters in Inhalation Formulations

For dry powder inhalers (DPIs), APIs must be within the 1–5 µm range to ensure deep lung deposition and therapeutic efficacy.

Microchem’s Analytical Testing Capabilities

We offer:

  • Laser diffraction (PSD)
  • Cascade impaction (MMAD)
  • Fines analysis (D10/D90)
  • Flowability and aerodynamic behavior

All data is integrated with formulation development efforts.

GMP Documentation and Interpretation

Results are released with validated analytical methods and reports fit for regulatory submission.
