Patent number: 11187639Abstract: Method of characterizing particles suspended in a fluid dispersant by light diffraction, comprising: obtaining measurement data from a detector element, the detector element being arranged to measure the intensity of scattered light; identifying a measurement contribution arising from light scattered by inhomogeneities in the dispersant; processing the measurement data to remove or separate the measurement contribution arising from light scattered by inhomogeneities in the dispersant; calculating a particle size distribution from the processed measurement. The detector element is one of a plurality of detector elements from which the measurement data is obtained. The detector elements are arranged to measure the intensity of scattered light at a plurality of scattering angles, the plurality of scattering angles distributed over a plurality of angles about an illumination axis.Type: GrantFiled: June 13, 2019Date of Patent: November 30, 2021Assignee: Malvern Panalytical LimitedInventors: Rhys Poolman, David Stringfellow, Nigel Lightfoot, Jason Cecil William Corbett
