Method of measuring the permeability of a material using thermogravimetric analysis techniques

摘要

A method for measuring the permeability of a material (55) using a thermogravimetric analyzer is disclosed. The permeability of the material is measured by sealing a sheet (55) of such material over an opening in a liquid (50)(or solid, or gas) filled receptacle (12). The sealed receptacle is than placed in a thermogravimetric analyzer wherein the weight of such receptacle is monitored as a function of time in a controlled environment.
