US Patent:

20120152745, Jun 21, 2012

Filed:

Dec 17, 2010

Appl. No.:

12/972412

Inventors:

Jason Cecil William Corbett - Hereford, GB
Malcolm Connah - Worcestershire, GB
Kevin Mattison - Sterling MA, US

International Classification:

G01N 27/447
G01N 27/453

US Classification:

204547, 204643

Abstract:

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.
