Oxygen Sensing

oxygen sensing

Optical oxygen sensors comprise an indicator fluorophore in a sol-gel host matrix that’s applied to an adhesive patch or fiber tip. The indicator changes optical properties in response to analytes in its environment and a fluorometer measures the response.

Ocean Insight optical oxygen sensing materials can be applied to various surfaces including probes and patches, making them customizable to each application. Because the sensors consume no oxygen, they can be used in continuous contact with viscous samples. Also, unlike oxygen electrodes, optical oxygen sensors do not require continuous stirring.

Advantages of Oxygen Sensing

  • Sensors detect molecular oxygen in gas and liquid phases across a wide range of temperatures and concentrations
  • Continuous sample contact: Optical oxygen sensors do not consume the sample
  • Rapid response time: Sensors respond within 1 second or less
  • Low-level detection: At the lowest oxygen concentrations, sensors can resolve to 0.004% oxygen at 1 atm
  • Multiple form factors: Sensors are available as probes, adhesive patches or integrated into biobags and other vessels
