Ammonia - Technical Specification

The Smart Storm direction Ammonia combination ISE is a traditional pH glass sensor with a refillable membrane cap. This electrode does not have the solid state advantage of the Ammonium ISE 3051 but is able to detect dissolved Ammonia down to around 50ppb. For successful operation NaOH ISAB should be added to the samples and standards to ensure all the Ammonium is converted to NH3. The analysis is best done in 100ml conical flasks to reduce the loss of NH3 gas.
