✦ Synopsis

vertical spacing is governed by the solubilities of the various esters.

At high flow rates, the permeation rates leveled off and became independent of flow in accordance with Eq. 4, wherein the permeation rate becomes only a function of the transport across the membrane. Thus, K and C determined the relative positions of the plateaus in Fig. 3.
