Subvisible particle analysis
Light obscuration tells you how many particles there are. Flow imaging shows you what they are — protein aggregates, silicone oil, air bubbles or foreign matter — so you can find the root cause.
QC labs testing parenterals, formulation teams, and cell and gene therapy developers.
Challenges we help solve
Light obscuration alone cannot tell protein aggregates from silicone oil droplets.
Low-contrast aggregates are under-counted by traditional methods.
Root-cause work needs images and morphology data, fast.
