O2 Sensors

 

Pre-Configured and Custom Oxygen Sensors

We offer a variety of highly stable fiber optic oxygen sensing options ranging from biological and medical applications to dissolved Oxygen in fuels, Petroleum products, solvents,  and other hydrocarbons.  For remote sensing we offer coated patches that adhere to the inside wall of the package, vessel window, or flow cell.  The coating on the patch will be selected for biological or hydrocarbon applications.  Readout is achieved using a probe (DOPO2) with with interchangeable tips which elimiantes the need for fiber coupling.

Principle of Operation:  A LED light source transmitts 450 nm light into the probe and the flourescence quenching of the O2 level is detected by the sinusoidal phase shift  of the incident light to the red shifted flourescnce signal.  Since this is a time-based measurement, it provides a system that is robust and unaffected by light losses when using the patches inside package or vessel window.  The patch size will be determined by the wall thickness since the light from the fiberoptic bundle is divergent.  For this reason, patch sizes can be made to any diameter so the fluoresccence effectively couples back into the fiber bundle and then to the fluorimeter.  

We offer both pre-configured O2 sensing systems (general purpose 0-22%O2 with a 25-35 deg C range) like the DOPO2 systems that has everything integrated into the probe.  We also offer custom solutions (e.g., needle-like probes or patches for non-invasive measurements).
