NO Microsensor
Measure minute concentrations of NO
Nitric oxide plays an important role in many biological processes; however, natural concentrations are often in the nanomolar range. The Unisense NO microsensor is characterized by a very high sensitivity, which enables you to measure minute concentrations of NO. Combined with a fast response time the Unisense NO microsensor is an excellent research tool for a broad range of tasks.
The sensor can be used equally well for measurements in tissue, air, or liquid, and is applied in a broad variety of research fields where non-destructive, fast and accurate measurements are required. The NO microsensor is designed for research applications within:
- Environmental sciences
- Biomedical sciences
- Biotechnology
- Wastewater
Microsensor technology:
The NO micro- and minisensors are Clark-type sensors measuring the external NO partial pressure. The working principle of the sensor is based on diffusion of NO through a silicone membrane to an NO oxidizing anode, which is polarized against an internal counter cathode. The resulting sensor signal is in the pA range and is measured by a high quality picoammeter e.g. the Unisense Microsensor Multimeter.
Compared to other standard NO sensors the Unisense NO microsensor has an extremely low consumption of max. 935 pmol/hour corresponding to 0,1 %/hour in a 1 mL 0,1uM NO sample.
