Le processus de perméation implique la diffusion de molécules qui forment le perméat, le plus souvent à travers une membrane ou une interface. La perméation est due à la diffusion; le perméat va se déplacer du milieu de forte concentration à celui de faible concentration à travers l'interface. Un matériau peut être semi-perméable, avec la présence d'une membrane semi-perméable. Seuls des molécules ou des ions avec certaines propriétés seront en mesure de diff… WebThe permeation source emits this material at a consistent flow rate at a given temperature. The permeation source is contained in an oven to control the temperature, and the emission rate (typically a few hundred nanograms per minute) is measured by successive weighings.
