General Info
Hylec Controls Oxygen Permeability Tester is based on the equal pressure method, and is professional applicable to the determination of oxygen transmission rate of film and package products, including plastic films, composite films, sheeting, plastic bottles, plastic bags and other packages.
Principle
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen flows outside.
