  • Bump Testing Ammonia (NH3) Sensors

    Exposure to very high concentrations of ammonia can kill the sensor leaving it useless for detection. Therefore, it is important to use a lower concentration of NH 3 gas for bump testing. Depending on what concentration of NH 3 you are using for the bump test, the length of time you will be applying the NH 3 should change. In most cases the Low

  • Electrochemical Detection of Ammonia Using a Thin Ionic

    Jan 01, 2015It is demonstrated that this ionic liquid film-based sensor can detect ammonia (NH3) at levels as low as 1 ppm in ambient conditions. Moreover, both amperometry and cyclic voltammetry are successfully applied to detect NH3. However, amperometric measurements are hampered by a decreasing sensitivity (‘fouling’) during NH3 exposure.Cited by: 13
