How it works

 

Multiple light scattering analysis of concentrated dispersions 
The optical sensor consists of a pulsed near-infrared light source and two synchronous detectors:
The transmission detector monitors light transmitted through the product;
The backscattering  detector receives light backscattered by the product.
The optical sensors acquire
transmission and backscattering signals as fast as every 0.1 seconds (0.1 to 10 seconds) and these signals are digitized by a current to voltage converter. The results are then displayed by the Turbiscan OL software indicating real time changes in transmission and backscattering intensities.




l & l*    mean path length of photons in the dispersion (in mm)

The backscattered (BS) and transmitted (T) light fluxes measured by the optical sensors change with the mean path length of photons in the dispersion:
l (for transmission) and l* (for backscattering).






These physical characterization parameters are directly related to particle diameter (d) and volume fraction (F)







g(d) = asymmetry factor
Qs(d) = scattering efficiency factor
r = tube radius
