Abstract:
Systems, methods and apparatus implementing techniques for separating and/or analyzing fluid mixtures. The techniques employ microfluidic separation devices that include an inlet port for receiving a fluid feed stream, a microscale fluid flow channel in fluid communication with the fluid inlet port, a phase equilibrium control region located along the fluid flow channel for controlling conditions including temperature and/or pressure to provide a thermal equilibrium, a capillary network in the temperature control region, a first outlet port in indirect fluid communication with the fluid flow channel through the capillary network, and a second outlet port in direct fluid communication with the fluid flow channel. A plurality of microfluidic separation devices can be coupled in fluidic communication to provide for separation of complex mixtures. The systems, methods and apparatus can be used to characterize fluid mixtures.
Abstract:
Fluid sensor methods and systems adapted for monitoring and/or controlling distillation operations in fluidic systems, such as batch distillation operations or continuous distillation operations, are disclosed. Preferred embodiments are directed to process monitoring and/or process control for unit operations involving endpoint determination of a distillation, for example, as applied to a liquid-component-switching operation (e.g., a solvent switching operation), a liquid-liquid separation operation, a solute concentration operation, a dispersed-phase concentration operation, among others.
Abstract:
Methods, apparatus and systems implementing techniques for screening compositions in a test environment. Test samples are exposed to one or more test fluids under controlled conditions. The test samples and/or test fluids are analyzed to detect an effect of the exposure.
