Patent ID: 8576396

Claim:
A device for measuring light scattering properties of a suspension which is fed through a sample cell and is irradiated by a monochrome collimated light beam, the device comprising: a sample cell ( 1 ) has a channel ( 2 ) which permits feed and discharge of the suspension, and which allows a monochrome collimated light beam ( 3 ) to pass in, pass through and pass out in the direction of the channel length, wherein a cell geometry of the sample cell ( 1 ) displays a curved surface ( 7 ), and the sample cell is formed from transparent material and focuses light ( 4 ) scattered horizontally in a specific angle by a curved surface ( 7 ) of the sample cell ( 1 ) onto a point outside the sample cell to achieve focussed light, and wherein light-sensitive detectors ( 5 ) are arranged in the point onto which the light is focussed so that the light-sensitive detectors collect the focussed light ( 4 ) which is scattered by a suspension and which passes through the channel and the transparent material of the sample cell ( 1 ).
