Apparatus and method for permeation testing of materials against chemicals

A permeation test cell for testing permeation of chemical contaminants through a material, the permeation test cell comprising:

• an upper body provided with one or more first vents for passing a first gaseous stream and a lower body provided with one or more second vents for passing a second gaseous stream, wherein the upper body and the lower body are sealed together after placing a contaminant on an upper side of a test sample placed between the upper body and the lower body;
• and
• one of the second vents of the lower body being configured to attach with a sorbent tube to accumulate the contaminant permeated through the test sample,
• wherein the apparatus is configured to receive:
• a weight on the test sample to impart pressure on the contaminant for forcing permeation of the contaminant through the test sample;
• and
• a perforated Polytetrafluoroethylene (PTFE) grid placed underneath the test sample to allow passage of the contaminant to the sorbent tube.
