ABSTRACT:
Disclosed is a method of determining a diffusion coefficient for a diffusant in a particulate. An inert gas is passed through a particulate containing the diffusant. A parameter that is proportional to the concentration of the diffusant in the inert gas is measured over a period of time and the slope of the linear portion of that relationship is determined and is multiplied by a constant.
