摘要

Method and apparatus for determining presence or absence of contamination in bottles or similar containers, in which a first fluid medium is introduced into a container, and then a second, different, fluid medium is introduced into the container to thus form a third fluid medium in the container. A portion of the third fluid medium is then removed from within the container by suction. Finally, the portion of the third fluid medium is sensed in a sensor apparatus to determine presence or absence of contamination in the portion of the third fluid medium.
