Investigations on the effect of flow rate, loading and other factors upon the effectiveness of radiochemical separations by ion exchange chromatography

  • R. Dybczyński


It is shown that, depending on the ion exchange system and experimental conditions, the plate height can either increase or decrease with flow rate. The results are interpreted using the modified Glueckauf equation containing an additional term which allows for longitudinal diffusion in the resin phase. A new method for estimating the diffusion coefficients in the resin phase is suggested. Different susceptibility of various chromatographic systems to loading effects is demonstrated and discussed. Other factors influencing the degree of separation like particle size, magnitude of distribution coefficients, temperature and resin cross-linking are briefly mentioned.
