O2 detection uses a little RedEye

RedEye™ Oxygen Patch, from Ocean Optics, is designed to provide accurate oxygen measurement in packaging and other enclosed containers for medical and pharmaceutical applications.

Using a combination of proprietary sensing material and optical sensing technologies the non-invasive patch enables quick readings of the presence or absence of oxygen, as well as providing quantitative measurements. Accurate measurement of oxygen concentration can have critical implications in medical and pharmaceutical applications; it can assure patient safety in point of care analysis and respiratory settings, or indicate a sterile seal on surgical instruments and drug packaging.

The self-adhesive RedEye patch can be integrated into the surface of sample containers such as blood bags, pill blister packs, or point of care analysis devices like disposable ventilator oxygen attachments, to permit non-invasive, through-the-package oxygen concentration measurements. Ocean Optics’ proprietary nano-porous sol-gel coating is non-reactive and keeps the sensor immobilized, protected from the package contents. Depending on the application, the simple presence of oxygen can be visually determined by color change with a handheld LED, or a fluorometer can be used to directly measure the exact oxygen level.

RedEye coatings are capable of monitoring low levels of oxygen in gas (to 0.005 per cent) and dissolved oxygen in liquids (to 20 ppb), as well as the higher oxygen levels present in cell culture and respiratory monitoring. In addition to medical and pharmaceutical uses, RedEye coatings are available for food, beverage, fuel and other hydrocarbon-based product applications.

Patches are manufactured to customer size specifications with one of Ocean Optics’ three coating formulations, depending on measurement needs. The RedEye can be integrated into packaging for continuous monitoring or used externally for post-production and R&D monitoring purposes.
