| description | The invention relates to a probe for detecting luminescent and/or light-scattering particles in flowing liquids, comprising a measurement cell having a pipeline channel through which the fluid to be measured flows, at least one transparent window in a wall of the pipeline, at least one light source for generating a dimensioned excitation light beam exciting the luminescent and/or light-scattering particles in the pipeline channel through the window in an optically bounded light volume, at least one detector receiving the light emitted by the luminescent and/or light-scattering particles through the window or through a further window, wherein the measurement cell is constructed so that the dimensioned excitation light beam and the emitted light are oriented perpendicular to each other, and each particle is displaced within the measurement volume parallel to the liquid flow, in a straight line at a fixed angle to the excitation light. The invention further relates to a method for detecting luminescent and/or light-scattering particles in flowing liquids as well as to the use of the probe according to the invention and the method for online monitoring of a production system, in particular a plastic production system or a wastewater treatment plant. |
