  • Method and apparatus for detecting leaks in packaging
    Patent number: 6050133
    Abstract: A method and apparatus are directed to non-destructive testing for a leak in a sealed package having an interior chamber formed of a gas-permeable portion and a non-gas-permeable portion. A temporary barrier having an aperture is formed to the gas-permeable portion to temporarily seal the gas-permeable portion of the sealed package except at the aperture. A tracer gas is applied through the aperture at the gas-permeable portion, whereby the tracer gas enters into the interior chamber. The concentration of tracer gas is measured at the exterior of the sealed package, thereby testing for a leak in the sealed package.
