Fiber Optic and Remote Oxygen Sensing.
We offer a variety of O2 sensing options ranging from biological materials to dissolved OS2 in solvents and hydrocarbon applications.  For remote sensing we offer coated patches that are adhered to the inside of transparent vesels or packaging materials (food).  This allows either short term or long term monitoring for packaging applications in food, medicine, bioreactors,  R&D and Biotechnology applications.  Read out is achieved with a fiber optic bundle probe connected to an Ocean Optics NeoFox phase flourimeter.   Via USB, the NeoFox viewer is a comprehensive software package that allows real time monitoring of the oxygen levels.  The NeoFox can also be use directly with a coated probe where a bifurcated fiber and splice bushing connects the probe to the fiber.  The NeoFox transmitts 450 nm light into the probe and the flourescence is detected by the phase shift of the incident light to the red shifted flourescnce signal.  Since this is a time-based measurement, it makes the system robust and unaffected by light losses through vessels (e.g., remote sensing) or in the probes.

For O2 sensing we recommend the Ocean Optics NeoFox phase fluourimeter combined with the NeoFox viewer, and temperature probe.  While our probes/patches can be  factory calibrated for different temperature ranges, we recommend real time monitoring of the temperature.

Our probes/pathces are extremely stable and are immune to bleaching which can occur in SolGel based sensors.

NEOFOX-GT Fluorimeter

The NeoFox-GT is a small footprint phase fluorimeter that couples with Ocean Optics’ oxygen sensor probes and patches to provide fast and reliable oxygen measurements in both gas and liquid phases.
