C230G Oxygen Transmission Rate Test System is designed and manufactured based on the coulometric sensor method (aka. equal pressure method) and conforms to ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high and medium barrier properties with high accuracy and high efficiency. The instrument features Labthink’s patented design of integrated test block consisting of three permeation cells. Equipped with a high precision coulometric sensor and Labthink’s professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate precisely, guaranteeing high sensitivity and excellent repeatability of test results. C230G is applicable to the determination of oxygen permeability of plastic films, sheeting, paper, and other packaging materials used in food, pharmaceutical, medical apparatus, consumer products, photovoltaic and electronic industries, etc. Optional accessories extend the capability to testing complete packages and systems such as bottles, pouches, cartons, blister packs, tubes and more.

Test Principle
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. The upper chamber contains oxygen or air and the lower 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 the signals and calculating the volume of oxygen measured by the sensors. For whole package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.
