There is a clear need for routine methods of analysis of the ligand concentration in affinity gels. Convenient methods are required for (a) monitoring the success of syntheticgrocedures, (b) studying leakage or other deterioration during the use of the gel and (c) studying the efYect of ligand conce
A technique developed by Millington and Peters (1969) was used to estimate diffusivities (K F ) from measurements of the dispersal of a tracer gas from a point source using Fickian diffusion equations. These estimates were found to be about an order of magnitude smaller than aerodynamic diffusivity
