Saturn DigiSizer Application

The light scattered by particles is only a portion of the total laser light scattered during analysis with the Saturn DigiSizer. The optical components of the analyzer and the dispersing liquid also scatter light; this is known as background scattering. The light scattering strength by the particles above that of the background is called the scattering signal fraction. In order to limit the effects of scattering noise, a threshold known as the Minimum signal fraction can be specified in the Saturn DigiSizer sample information file. Any collected data that do not exceed the background by this specified intensity percentage are not used in particle size calculations.
