Particle Characterization

Particle Characterization Core Facility

Significant improvements in analytical technology to quantify and characterize subvisible (1 – 100 µm) and submicron particles (≤1 µm) have prompted the regulatory agencies to require characterization of particles in these size ranges.

Multiple orthogonal methods are required to span the entire range and to accurately characterize the particle profile, as each instrument possesses limitations based on the detection strategy and sample solution properties. These limitations must be well understood to generate high-quality data.
