We use pervaporation-based microfluidic devices to concentrate species in aqueous solutions with
spatial and temporal control of the process. Using experiments and modeling, we quantitatively describe
the advection-diffusion behavior of the concentration field of various solutions (electrolytes, colloids, etc.)
and demonstrate the potential of these devices as universal tools for the kinetic exploration of the phases
and textures that form upon concentration.
