Time domain solutions applicable to the GC pulse dispersion experiment are presented in the form of dimensionless numerical plots. It is shown that when the particles are nonporous, or diffusion in both the macro-and micropore systems is rapid, a Gaussian peak results. In this case the peak broadeni
A mathematical model is developed which describes the pulse response of a chromatographic column packed with crystal zxolite powder, thus allowing the crystal diffusivity to be determined independently of the pellet diffusivity which is present in more conventional beds. This continuum model allows
Experimental results are reported for the adsorption of propane and n-butane in a column packed with Linde 5A ZeoIite crystals, and methane, propane, a-and ire-butane in a column packed with silicalite crystals. The adsorption equilibrium constant K and crystal diffusivity 0, were obtained at differ
