    Sensing Oxygen via the Patented OxyDot (O2xyDot®)

    Oxygen Measurement Technique
    The oxygen measurement technique is based upon the fluorescence quenching of a metal organic fluorescent dye immobilized in a gas permeable hydrophobic polymer. The dye absorbs light in the blue region and fluoresces within the red region of the spectrum. The presence of oxygen quenches the fluorescent light from the dye as well as its lifetime.

    The quenching process is a purely collisional dynamic where the energy from the excited fluorescent dye is transferred to the oxygen molecule during a collision, hence, reducing the emission intensity as well as the fluorescent lifetime of the dye. Thus, the oxygen content of the enclosed space is not changed by the measurement process. Fluorescence Decay and Oxygen Measurement. The change in the emission intensity and lifetime is related to the oxygen partial pressure and can be calibrated to determine the oxygen concentration.

    The measurement is passive, totally reversible and no oxygen is consumed in the process. The fluorescence lifetime is reduced due to the presence of oxygen; this change is used to make a powerful sensor that has a large dynamic range. No matter what your oxygen measurement or monitoring requirement, OxySense can provide an easy-to-use, efficient and economic oxygen analyzer / oxygen measurement system.
