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 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, selectivity and transmission rate in separation membranes can be obtained by the application of chromatography analysis technology.
This instrument is applicable to the determination of:
| Permeance | Test the permeance of separation membranes to various components of sole gas or mixed gas under a certain condition |
|---|
| Selectivity | Test the selectivity of separation membranes to various components of mixed gas under a certain condition |
|---|
| Transmission Rate | Test the transmission rate of separation membranes to various components of sole gas or mixed gas under a certain condition |
|---|
