Particle size Distribution D10 is also written as X10, D(0,1) or X(0,1). It represents the particle diameter corresponding to 10% cumulative (from 0 to ) undersize particle size distribution. In other words, if particle size D10 is 7.8um, we can say 10% of the particles in the tested sample are smaller than 7.8 micrometer, or the percentage of particles smaller than 7.8 micrometer is 10%.

Particle Size Distribution

2011/8/8The particle size distribution was measured using laser light diffraction particle size analyzer (LS 230, Coulter-Beckman, Germany). This allows measuring particle sizes from 0.04 μm to 2000 μm by combiniation of laser light scattering for measuring the coarse particles and polarization intensity differential scattering (PIDS) for measuring the finer particles.

Aerodynamic Particle Size Distribution

Within each dose of an inhaler device, a consistent distribution of specifically-sized particles is required depending on the condition being treated. Among many other factors, the size distribution of the particles within each inhaler dose, or a dose of any inhaler device, indicates where the drug lands within the respiratory system and how quickly it is dissolved into the user's system.
