  • Comparison of low cost measurement techniques for long-term

    Key requirements were for: a low cost system, simplicity and durability to enable a postal exchange with local site operators, a precision of < +/- 20% for monthly sampling at expected NH3 concentrations of 1-2 micrograms m-3, a detection limit sufficient to resolve the small NH3 concentrations (< 0.2 microgram m-3) expected in remote parts of the UK, and a quantitative means to establish quality control.

  • Electrochemical Detection of Ammonia Using a Thin Ionic

    Jan 01, 2015 · It 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.
