  • Method and device for sampling dispersed streams of material
    Patent number: 6357305
    Abstract: The invention concerns a process for sampling disperse material flows in which an analysis substream is extracted from a process mainstream for subsequent analysis. According to the invention, the analysis substream is removed from the process mainstream via an extraction area. The extraction area is smaller than the process substream cross section and defined independently of this. The extraction area travels along an orbital curve across the process mainstream cross section during the removal of the analysis substream. The invention also relates to an apparatus for performing the process according to the invention.
