<p>Device for measuring the molecular diffusion coefficient, characterized in that it contains a holder (1-2) of non-conductive material for the porous medium (4), a buffer receptacle (5) on two ends of the holder (1-2) situated opposite one another, two electrodes (6 and 7), namely one in each buffer receptacle, and a source to generate a potential gradient (9) between the electrodes (6 and 7). The method is characterized in that a potential gradient is applied to an amount of the porous medium, so that the diffusion process is accelerated.</p> |
