Abstract
A cell for measuring the permeation of a target gas through a sample includes upstream and downstream chambers connected by an opening, a primary seal in contact with the bottom of the upstream chamber and surrounding the opening, and a removable sample holder and means for assembling the sample holder in the cell. Upper and lower frames included in the sample holder are each provided with a through opening. The sample holder includes means for assembling the sample in the sample holder and a first seal flush with the front surface of the lower frame, and surrounding the through opening of the lower frame. In the lower frame of the sample holder, a second seal is flush with the front surface of the lower frame, surrounding the through opening of the lower frame, and being surrounded with the first seal, and a second channel emerging between the two secondary seals.
