Abstract:
A method and system for researching and developing and/or optimizing new catalysts and products in a combinatorial manner is disclosed. The method begins with starting components or a ligand library and provides methods of creating catalyst or product libraries, which are then tested in a reaction of interest. The system uses methods of robotic handling for moving libraries from station to station. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial catalyst libraries, but also offer significant advantages over conventional experimental methods as well.
Abstract:
A method for characterizing a polymer sample that includes the steps of withdrawing a polymer sample from a sample container into an injection probe of an auto- sampler where the probe is heated to maintain the withdrawn sample at a temperature of not less than about 75 degrees Celsius while resident in the probe. The heated injection probe resides in a first environment maintained at about ambient temperature while withdrawing the polymer sample. The method further includes loading at least a portion of the withdrawn sample into an injection port or a loading port of a liquid chromatography system where the injection port or loading port is adaptable for fluid communication with a chromatographic column. The chromatographic column resides in a heated second environment maintained at a temperature of not less than about 75 degrees Celsius. The loaded sample is injected into a mobile phase of the liquid chromatography system. The sample is maintained at a temperature but not les s than about 75 degrees Celsius during a period of time including from when the sample is withdrawn from the sample container to when the sample is within the heated second environment. The injected sample is chromatographically separated and a property of the sample or a composition thereof is detected.

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.
