The LUMiSpoc is a highly developed single particle scattered light photometer for determining the particle size distribution and particle concentration of nano- and microparticles in suspensions and emulsions. The measurement is possible with the highest resolution in a dynamic range from 40 nm to 10 µm.
In collaboration with the metrology institute Physikalisch-Technische Bundesanstalt (PTB), the measurement technology provider LUM GmbH developed the LUMiSpoc as part of a technology transfer project for the multidimensional characterization of nanoparticles supported by the BMWi and delivered it for the first time in 2021. Up to 10,000 particles can be analyzed per second. Based on SPLS (Single Particle Light-Scattering) technology, the LUMiSpoc measures the intensity of the light scattered by each individual nano- and microparticle in different directions as they pass through a highly focused laser beam with a tiny cross-section one after the other.
Particle separation is achieved by hydrodynamic focusing of the sample stream. The volume-calibrated sample flow enables precise measurement of the particle concentration. The LUMiSpoc analyzes very broad, multimodal or polydisperse real particle suspensions over several orders of magnitude without any change of hardware and determines the smallest size differences down to the nanometer range, even for very high initial concentrations. The first devices have already been handed over to a global pharmaceutical company in the EU for the development of a corona vaccine and to a renowned national academic institution.
