Oxygen Microsensors
Sensor tip thinner than a hair (< 50 µm) Integrate & measure on-the-spot
- Profiling of biofilms and sediments
- Insertion in plant and animal tissue
- Micro-respiration systems
- Micro-invasive measurement in packages
Needle-type oxygen microsensors are miniaturized chemical optical oxygen sensors designed for all research and packaging applications where a small tip size (< 50 µm) and fast response time (t90 < 1s) are necessary. The optical oxygen microsensors are based on a 140 µm silica fiber and are available with two different sensor tip diameters, a < 50 µm tapered tip and a 140 µm flat-broken tip. The oxygen micro-sensors are mounted in different housings (needle-type housing, implantable) and offer a unique research tool for investigating systems where micro-invasive, small and robust sensors are needed.
Features
- High spatial resolution (< 50 µm)
- High temporal resolution (t90 < 1s)
- Measurement range from 1 ppb up to 22.5 ppm dissolved oxygen
- No consumption of oxygen
- Signal independent on flow velocity
- Measures oxygen in liquids as well as in gas phase
