Abstract
A method for controlling pervaporation through a membrane includes assessing the vapor pressure of each component material of a mobile phase disposed on a retentate side of the membrane, and maintaining a designed environment on a permeate side of the membrane. The environment maintained on the permeate side of the membrane contains partial pressures of selected component materials of the mobile phase at a level substantially equal to or greater than the respective vapor pressures thereof.
