The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of mixed gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between the two chambers. The gas permeates through the specimen from higher pressure side into the lower side and is further detected by gas chromatograph. The permeance of sole gas or mixed gas as well as the corresponding transmission rate can be obtained by the application of chromatography analysis technology.
This instrument is applicable to the determination of:
| The Overall Permeance of Test Gases | Test the overall permeance of various films to sole or mixed gas under a certain condition |
|---|
| The Permeance of Sole Component | Test the permeance of various films to sole component of mixed gas under a certain condition |
|---|
| Transmission Rate | Test the transmission rate of various films to various components of mixed gas under a certain condition |
|---|
