Abstract
Microfluidics is becoming increasingly more interesting for chemical engineering applications. This article takes a closer look at the possibilities of performing a precipitation reaction in a microfluidic device. This specific type of reaction demands for instance fast mixing. We take sodium chloride precipitation as a model anti-solvent precipitation reaction. Effective mixing is achieved by applying an electric field over the fluid. The dispersion of a plug is measured when it is transported by pressure driven flow or electroosmotic flow. These two different types of transportation are investigated.
