Fluid sensor methods and systems adapted for monitoring and/or controlling distillation operations in fluidic systems, such as bath 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 switehing operation), a liquid-liquid separation operation, a solute concentration operation, a dispersed- phase concentration operation, among others.
