Abstract
A method of performing a diffusion test includes clamping a membrane to a body such that a first surface of the membrane is in fluid communication with an interior chamber of the body and a second surface of the membrane is exposed to ambient air, flowing a substance through the ambient air such that at least a portion of the substance lands on the second surface while the membrane is vertically oriented, and determining a concentration of the substance in the interior chamber after some of the substance has diffused through the membrane.
