NH3-Sensor PPB.

Highly selective ppb-level detection of NH3 and NO2 gas ...

The sensor showed a highly sensitive detection of NH3 and NO2 gas down to ppb-level. Furthermore, the sensor response changed in opposite direction to reducing NH3 and oxidizing NO2 gases, which shows that our sensor can be utilized in the selective detection of NH3 and NO2.", keywords = "Gas sensor, Indium tin oxide, Nanoparticle, Self-assembly", author = "Lee, {Dong Jin} and Jonghyurk Park ...

9130T Chemiluminescent Ammonia Gas Analyzer

The Model 9130T NH3 analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-20,000 ppb using the chemiluminescence principle and an external ammonia converter and sampling system. Ranges are user selectable in 1 ppb increments and auto ranging is available. Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials. The …

Micromachined NH3 Gas Sensor with ppb-level Sensitivity ...

2011-01-01· The sensor has been fabricated and tested. Thermal efficiency of the heater was measured to be 10 oC/mW. The optimal working temperature was found to be around 300 oC, and the sensor could detect NH3 gas at ppb concentration in a background of wet air. The nano-gap effect of the interdigitated electrodes in improvement of the sensitivity was ...
