LUMiSpoc

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.
