Diffusion measurement in gels
Forskningsoutput: Tidskriftsbidrag › Översiktsartikel
Methods for measuring diffusion coefficients in gels are reviewed, and their capacities, limitations and requirements are briefly discussed. With four of these methods, i.e., the diaphragm cell, uptake/release from beads, holographic laser interferometry and nuclear magnetic resonance (FT-PGSE), a comparison is made with regard to accuracy and precision. The comparison is based on a number of studies in which the diffusion coefficient of ethanol in agarose gel has been measured. It is concluded that the diaphragm cell and nuclear magnetic resonance (FT-PGSE) are very accurate and precise.
