Gas membrane separation technology utilizes the different permeability of polymer gas separation membrane materials to different gases in the mixed gas of raw materials. The pressure difference between the gases on both sides of the polymer gas separation membrane is used as a driving force to obtain gas enriched materials with high permeability on the permeation side and separated gases that are not easily enriched on the permeation side, thereby achieving gas separation.

The ideal gas separation membrane material should have high breathability and good gas permeability selectivity, high mechanical strength, excellent thermal and chemical stability, and excellent film-forming processing performance. The gas permeability of gas separation membranes for separating gas components is a key indicator of technical development and research for various manufacturers.

The SYSTESTER series membrane separation testing analyzer is suitable for testing the selectivity, separation rate, and other performance of various gas separation membranes, such as roll membranes, hollow membranes, flat membranes, ceramic membranes, tubular membranes, and pervaporation membranes. By utilizing the principle of differential pressure testing, it is possible to achieve qualitative and quantitative determination of the permeation amount, selectivity, and permeation rate of each component of a single or mixed test gas; Circulating medium temperature control, built-in temperature sensor in the testing chamber, real-time monitoring of actual temperature for performance testing of separation membranes at any temperature within the range, meeting the research needs of various scientific research institutions and universities for analyzing and improving the barrier performance of polymer gas separation membrane materials.

Under specified temperature conditions, a gas separation membrane sample is used to separate the permeation chamber. One side is a mixture of gas at a certain pressure, and the other side is evacuated. This creates a certain pressure difference between the mixed gas on both sides of the polymer gas separation membrane sample, and the gas will pass through the membrane and enter the low-pressure side; Then it is carried into the separation chamber by the carrier gas flow, and the content of each gas in the carrier gas is measured by the FID hydrogen flame ionization detector, and the amount of each gas passing through the unit area of the sample per unit time is calculated.
