i-Sepamate 7800 Separation Membrane Permeability Analyzer ---Film Test

Product catalog summary

Scope
The i-Sepamate 7800 Separation Membrane Permeability Analyzer is designed to measure the gas transmission volume, permeability rate, and selectivity of single or mixed gases through separation membranes under specified conditions.

Test Procedures

Specimen Preparation: Prepare test specimens ensuring uniform thickness and absence of defects. Identify the direction of permeation and avoid contamination during cutting.
Gas Setup: Open the main valve for test and carrier gases (helium), adjust output pressure, power on the instrument, and check the gas outlet with a flow meter.
Parameter Setup: Configure the gas chromatograph parameters.
Blank Test: Clean the test cell, tighten chambers without a specimen, perform a blank test, and save the report.
Specimen Placement: Apply vacuum grease, place filter paper and specimen on the lower test chamber ensuring tight contact.
Specimen Test: Set parameters and start the test, which runs automatically.
Data Collection: Analyze collected gases with GC, save chromatogram, and calculate results. View and print the complete test report.
Post-Test Procedure: Cut off gas supply if no further tests are planned shortly to prevent accidents.

i-Sepamate 7800 Separation Membrane Permeability Analyzer ---Film Test-1

i-Sepamate 7800 Separation Membrane Permeability Analyzer ---Film Test Scope i-Sepamate 7800 Separation Membrane Permeability Analyzer is designed to determine the gas transmission volume, permeability rate and selectivity of single gas or mixed gases for separation membrane under specified conditions. Test Procedures A: Prepare test specimens according to specific standards. The test specimen should be of uniform thickness and should be free of wrinkles, creases, pinholes, or grease. The direction of permeation should be identified. Extreme care should be taken when cutting the specimen to avoid any contamination.

D: Wipe off the test cell and tighten the upper test chamber and lower test chamber with no test specimen placed in. Then turn on the vacuum pump and set up test parameters for blank test. Then start the blank test and save test report after the test is finished. Establish method for blank test. E: Apply a certain amount of vacuum grease on the outer surface 2mm around the hollow groove of lower test chamber and place a piece of filter paper (diameter is 20mm) on the hollow groove. Then place the prepared specimen on the lower test chamber and make sure the test specimen contacts the lower test...
