Abstract: A system and method for nondestructive detection of gas in a sealed container. The system includes a light source housed in a light source housing and configured to emit a light beam for absorption in a substance to be measured, a detector housed in a detector housing and configured to detect the emitted light beam, a zone that accepts one or more of the sealed containers, each container being substantially optically transparent and containing the substance to be measured, the zone located between the detector and the light source, the light source configured to transmit the light beam through the zone, and a light source purging system comprising a light source channel surrounding the light source and positioned between the light source and the housing, the light source channel configured to expel purge gas from a purge gas source into the zone.

Abstract: A system and method for nondestructive automated headspace analysis. The system includes a container conveyor that conveys a plurality of generally optically transparent sealed test containers through a pre-inspection region, an inspection region and a post-inspection region of the container conveyor, and that conveys at least one sealed reference container, through the inspection region. Also included is a zone including a laser emitter and a sensor located in the inspection region and arranged such that the laser source emits a laser beam such that it intersects with a container movement path. The conveyor alternatingly conveys test containers and reference containers through the zone.
