  • Method and apparatus for measuring ultralow water permeation
    Publication number: 20040083796
    Abstract: Method and apparatus for testing ultralow moisture permeation through a sample such as a thin barrier film by exposing one surface of a sample to be tested for moisture permeation to a predetermined humidity of HTO. The HTO permeating therethrough is collected in a stream of dry gas, preferably methane, at a known flow rate, and monitored for its radioactivity content. Monitoring over a period of time and appropriate conversion allows accurate assessment of even permeation rates measured as very low fractions of a gram of water per square meter per day.
