FLUID PERMEATION TESTING APPARATUS EMPLOYING MASS SPECTROMETRY
摘要
<p>A fluid permeation testing apparatus provides for filling a first cavity of a test cell with a test fluid and filling a second cavity of the test cell with a challenge fluid. The challenge fluid comprises at least one analyte useful for testing permeation of the challenge fluid through a test film that separates the first and second cavities. Samples of the test fluid in the first cavity are introduced to a mass spectrometer, such as in a pulsed manner, without substantially changing the total pressure in first cavity. Samples of the test fluid in the first cavity may be introduced to the mass spectrometer while maintaining substantially balanced total pressures in the first and second cavities.</p>
