Unprecedented Resolution: New Single Particle Optical Counter for Nanoparticles and Microparticles

Particle size, size distribution and particle count

Particle size, size distribution and particle count are major characteristics in the field of particle technology. Contamination analysis and classification of nanomaterials according 2011/696/EU require precise data of the number based particle size distribution and particle concentration.

LUM GmbH introduces a new measuring instrument, developed by LUM GmbH and designed by the world-famous designer Luigi Colani. 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 a dynamic range from below 100 nm to a few micrometers.

Powered by SPLS-Technology (Single Particle Light-Scattering) the LUMiSpoc records light scattered into different directions from individual nano- and micro particles passing a focused laser beam of non-spherical cross-section. Particle separation is achieved by hydrodynamic focusing of sample flow. Volume calibrated sample flow allows for accurate measurement of particle concentration.

The LUMiSpoc analyses multimodal and very broad dispersed real-world particles and determines smallest size differences down to the nanometer range.
