RedEye Oxygen Sensing Patches
Easy to use, peel-and-stick indicator patches measure oxygen safely and non-invasively in sealed packaging and containers used in medical, pharmaceutical and food applications. They can be applied to flexible substrates of essentially any shape or size, and these patches can be adhered to a transparent vessel or process line. Using a combination of proprietary sensing material and measuring technologies, this patch enables rapid, quantitative determination of oxygen levels.
RedEye® coatings are capable of monitoring low levels of oxygen in gas (0.01%) and dissolved oxygen in liquids (4 ppb), as well as the higher oxygen levels present in cell culture and respiratory monitoring.
Non-invasive monitoring with RedEye® indicator patches
Measurements of sensor patch fluorescence are quickly and conveniently through the container wall using a fiber optic probe. This opens the door to applications that require monitoring of closed systems, such as biological processes, food and beverage packaging, and laboratory apparatuses.
Patches are interior to the sample packaging, container, or chamber, while probe remains outside.
