Abstract

Methods, systems and devices are described for rapid characterization and screening of liquid samples to determine properties (e.g., particle size, particle size distribution, molar mass and/or molar mass distribution) thereof with static light scattering and/or dynamic light scattering. The liquid samples can be solutions, emulsions, suspensions or dispersions. One method, includes providing a vessel containing a liquid sample having an exposed surface that defines a gas-liquid sample interface, and analyzing the sample by light scattering methods that include transmitting light through the gas-liquid sample interface into the sample, and detecting light scattered from the sample or from a component thereof. Additional methods are directed to characterizing a plurality of liquid samples or components thereof. The methods, systems, and devices have applications in high-throughput screening, and particularly, in combinatorial materials research and in industrial process control.
