This example applies the Electrophoretic Transport and Laminar Flow interfaces to model isoelectric separation in a free-flow electrophoresis device. A stream containing six different ionic species is shown to be divided into pure component streams by means of migrative transport in an ... En savoir plus
For an electrochemical reaction to occur, the reacting species usually needs to adsorb to the electrode surface before undergoing reduction or oxidation, after which the resulting product species desorbs back into the electrolyte. If the rate of adsorption or desorption is slow in ... En savoir plus
Crystallization is a key separation process in e.g. pharmaceuticals production. It is the process by which a chemical species is separated from solution by forming a crystal. To achieve the required product properties, control over the crystal particle size distribution is necessary. ... En savoir plus
