Principles
Film:
The specimen is clamped between the upper and lower chambers. The upper chamber is purged with an oxygen stream while the lower chamber is purged with a nitrogen stream. Due to the oxygen concentration gradient, oxygen molecules permeate through the specimen and are carried to a coulometric sensor, which generates a proportional signal from which the oxygen transmission rate and permeability coefficient are calculated.
Package:
The package is mounted on the lower chamber with the outside exposed to air or a pure oxygen stream and the inside purged by a nitrogen stream. Oxygen permeates through the package wall, and the penetrated molecules are carried to the coulometric sensor to determine the oxygen transmission rate.
