Abstract
A method and an apparatus for detecting a defect in a sealed container are provided. The method includes: placing the sealed container in a pressure chamber; filling the chamber with a liquid that is saturated by a test gas such that the sealed container is fully submerged; subjecting the chamber to a pressurized volume of a gaseous mixture that includes the test gas, and then removing the sealed container from the chamber; performing a laser-based headspace analysis of the sealed container in order to measure a partial pressure of the test gas; and using a result thereof to determine whether the sealed container has the defect. The defect may be located on a body of the sealed container that is at or below a level of a product that is contained within the sealed container.
