Fiber Optic Oxygen Meter for Microsensors

A generation of sensors based on luminescence lifetime

• Oxygen is not consumed during the experiment
• Immune to electrical and magnetic interference
• Excellent long-term stability
• No lengthy polarization necessary (like Clark-type O2 electrodes)
• Fast response time < 0.5 s for MicroTip sensors
• Probe size of MicroTip sensors as small as 50 µm
• Measurement is feasible in dry gas
• Optical isolation of sensor tip available for fluorescent or photosynthetically active samples
• The sensors are not included within the system
