Using the LUMiSpoc® single particle counter and sizer to develop Opti-Count® nanoscale number concentration reference materials
2025, English
Accurate nanoparticle characterization just got easier.
The LUMiSpoc® single particle optical counter measures particles from 40 nm to 5 µm with highly reproducible number-weighted size distributions and concentrations.
Combined with breakthrough Opti-Count® reference materials, the first traceable, number-based standards at 400 nm, it enables consistent, reliable nanoparticle analysis like never before.
