  • Subjects: Instruments, Particle Characterization, Product Development/Formulation, Testing, Validation, and Regulatory Compliance
This is the second in a two-part educational series discussing potential pitfalls in testing OIPs and ways to avoid them. The first article will discuss aerodynamic particle size distribution (APSD).

This article focuses on total emitted mass and related metrics, with the purpose of identifying potential pitfalls in set-up, execution and analysis that could obscure the findings, and therefore the interpretation of data, that are derived from such measurements.
