LUMiSpoc Counter PSA
The LUMiSpoc is a highly advanced single particle scattered light photometer 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 one after another the focus of a violet laser beam. The forward and sideward scattered light from each particle is detected and processed simultaneously by powerful optics and electronics (SPLS-Technology). The LUMiSpoc analyses multimodal and very broad dispersed real world particles in suspensions and emulsions and determines smallest size differences down to the nanometer range. Volume calibrated sample flow allows for accurate measurement of particle concentration.
