SPLS-Technology - Advanced technology for effective sizing and counting of single particles from nano- to microscale

Single Particle Light-Scattering Technology (SPLS) records light scattered into different directions from individual nano- and micro particles passing a focused laser beam of non-spherical cross-section.

The line-up of individual particles in a single line is achieved by hydro-dynamic focusing in an optical flow cell. Basically, a central sample stream and a surrounding sheath stream are created due to a pressure difference. The sheath flow creates a kind of fluid wall for the sample stream and prevents mechanical blockages. Cross section of sample stream can be dynamically adjusted (by factor 35) with no changes of the mechanical parts to meet the non-coincidence requirements of even higher concentrated samples.

If a particle crosses the laser beam the light is scattered in all directions and forward and sideward scatter are recorded simultaneously by means of two PMTs, and after amplification and digitization analysed in real-time. Obtained characteristics for individual particles, as scatter intensity heights, are sorted in up to 4.2x106 channels and high-resolution count distribution displayed at touch screen. Classified intensities are converted into particle size distribution density by the theory of Mie. Measurement, data storage and analysis are powered by software platform SEPView®.

A great advantage is simultaneous determining the particle concentration for each identified size fraction.

SPLS-Technology enables you a deep insight into complex nano- and submicro-particulate systems, which helps you to design tailored particles and dispersions.
