| titleOfInvention | Method and apparatus for test gas leak detection |
| abstract | A method for forming a composite film with low temperature dependence is provided. A leak detector includes a leak detector inlet for receiving a test gas, a vacuum pump connected to the leak detector inlet, and a test gas sensing connected to the leak detector inlet via a passage. A membrane that is permeable to a unit and to the test gas and is disposed in the passage between the leak detector inlet and the test gas sensing unit, wherein T 0 is a design temperature for the test gas. and a film having a permeability that varies less than 5 percent for the temperature range of T 0 -20K~T 0 + 20K to some time. In addition, a method is provided for forming a composite membrane comprising a semipermeable membrane and a porous membrane. In addition, a leak reference including a composite membrane is provided.
