Abstract
A high-throughput optical suspension characterization instrument is disclosed, which can include hydraulically separate and at least partially transparent sample containers. A selection mechanism is operative to selectively direct light from a light source () through different ones of the sample containers along an optical axis, and an off-axis scattering detector () is responsive to scattered light from the light source after it has interacted with a sample. Phase analysis light scattering is used to determine the electrophoretic mobility and zeta potential of samples. A second instrument is disclosed, wherein all sample containers are illuminated simultaneously. Transmitted light is collected by a camera. The electrophoretic mobility and hydrodynamic size of the samples may be determined.
