LUMiSpoc - Single Particle Count and Size Analyzer
The LUMiSpoc is a new-generation optical liquid particle counter and particle sizer. It combines the patented Single Particle Light-Scattering Technology (SPLS) with hydrodynamic focusing, giving you unprecedented dynamic range and accuracy in the nanometer and micron-size particle range.
Single Particle Light-Scattering Technology® (SPLS) is a technique by which both forward and sideward particle scattering characteristics are simultaneously measured and recorded.
Single particles are lined up in a single file by hydro-dynamic focusing in a specially designed optical flow cell. The flow cell channels all particles to the center of the flow stream. The surrounding sheath flow acts as a liquid wall, preventing mechanical blockage and ensuring all particles are fed through the detector and counted.
Additionally, the cross-section of the sample flow can be adjusted dynamically (by factor 35) with no changes to the mechanical parts. This allows you to work in a broad sample concentration range.
When a single particle crosses the laser beam, the light is scattered in all directions. Forward and sideward scattering of light are recorded simultaneously using two photomultipliers and are analyzed in real-time after amplification and digitalization.
The scattered light intensities determined for each particle are sorted in over 1 million bins and displayed as a high-resolution bar chart stating the count distribution on an easy-to-use touch screen.
The Mie theory converts Classified intensities into particle size distribution density. Measurement, data storage, and analysis are powered by the software platform SEPView®.
SPLS-Technology enables you to analyze nanoparticle and micron-particle-sized emulsions and suspensions correctly.
The instrument features a responsive large touch-screen interface, fully automated cleaning cycles, and many other user-friendly features that ensure a fun and engaging user experience.
Additional sophisticated data analysis can be performed using the powerful SepView software.
