Product Info LUMiSpoc

The LUMiSpoc® is a highly advanced single particle light-scattering flow cytometer that measures particle size distribution and particle concentration of nano- and microparticles in suspensions and emulsions with an unparalleled resolution and dynamic range.

Particles are separated by hydrodynamic focusing in the measuring cell and pass the focus of a violet laser beam one after another. By powerful optics and electronics , the forward and sideward scattered light from each particle is detected and processed simultaneously.

The technology used is called SPLS (single particle light-scattering, SPLS-Technology®). It records light that is scattered into different directions by single nano- and micro particles while passing a focused laser beam of non-spherical cross-section. It enables you to get a deep insight into complex nano- and submicro-particulate systems, which helps you to design tailored particles and dispersions.

LUMiSpoc® - the new standard in nano particle counting.
