  • Ti3C2 MXene-Based Sensors with High Selectivity for NH3

    Thereafter, the sensors were used to detect various gases (CH4, H2S, H2O, NH3, NO, ethanol, methanol, and acetone) with a concentration of 500 ppm at room temperature. Ti3C2 MXene-based sensors have high selectivity to NH3 compared with other gases. The response to NH3 was 6.13%, which was four times the second highest response (1.5% to ethanol gas).

  • Ammonia Gas Detection- system codes and design

    CO2 detection is required instead of ammonia detection in refrigerated and process areas. Detection system design and output functions are similar with the difference being the CO2 sensor selected, warning setpoints at 0.5% (OSHA 8 hour TWA) and alarm setpoints at 1.0%. One controller can support a combination of ammonia and CO2 sensors.
