Publication number: 20230160851Abstract: In one general aspect, an electrophoretic measurement method is disclosed that includes providing a vessel that holds a dispersant, providing a first electrode immersed in the dispersant, and providing a second electrode immersed in the dispersant. A sample is placed at a location within the dispersant between the first and second electrodes with the sample being separated from the electrodes, an alternating electric field is applied across the electrodes, and the sample is illuminated with temporally coherent light. A frequency shift is detected in light from the step of illuminating that has interacted with the sample during the step of applying an alternating electric field, and a property of the sample is derived based on results of the step of detecting.Type: ApplicationFiled: May 11, 2020Publication date: May 25, 2023Applicant: Malvern Panalytical LimitedInventors: Jason Cecil William Corbett, Malcolm Connah, Kevin Mattison

Patent number: 8614792Abstract: In one general aspect, a method of measuring characteristics of particles in a liquid sample disclosed. The method includes supporting the liquid sample by surface tension and illuminating the supported liquid sample along an illumination axis with spatially coherent light so as to cause the coherent light to be scattered across a scattering zone.
