This work reports a new technique for the rapid measurement of diffusion coefficients using a special flow cell called a SPLITT cell. Such SPLITT cells, designed for continuous SPLITT fractionation, utilize differential transport across a thin (approximately 100 microns) ribbonlike lamina flowing th
It is evident that the study of diffusion of molecules confined in microporous material, such as zeolites, gives valuable information about the chemical and geometrical properties of the pores. However, due to the limited size of the microporous crystallites or grains, and a non-zero observation tim
