Oxygen Ingress Measurement

A new non-invasive and non-destructive fiber optic oxygen meter determines oxygen permeability of plastic bottles and containers. Trace oxygen concentrations inside the package are measured. Ideal for assurance, production and quality control, this system incorporates the latest state-of-the-art in optical-chemical sensor technology. Permeation rates can be confirmed without piercing the package or bottle.

The sensing principle is based on a fluorescence quenching method enabling oxygen measurements in a non-destructive way. A trace oxygen sensor spot is placed inside the transparent bottle or package and a fiber optic cable is positioned on the outside. The luminescence lifetime of the oxygen-sensitive spot changes with the oxygen concentration and is therefore acting as the oxygen dependent parameter.
