Oxygen-sensing technology

Photonic BioSystems, Inc. has developed new technology for measuring oxygen non-invasively inside sealed packages for food, beverage, medical, pharmaceutical, and electronics applications.

Using remote optical interrogation, it eliminates destructive package testing and enables noncontact, rapid, real-time O2 measurements.

This approach makes "smart packages" by incorporating a small amount of an oxygen-sensitive luminescent dye inside the package film itself. The technology is diverse, capable of measuring O2 either in the gas phase environment of a dry package, in the headspace of a liquid package, or of dissolved-oxygen in fluids and beverages.

This works for flexible film packages, rigid containers, bottles, vials, caps, and other sealed vessels.
