ammonia 13.8 ppm


ppb level analysis

The shown chromatogram demonstrates the analysis of 13.8 ppm ammonia. Further dilution proved a lower limit of detection down to < 100 ppb. Note the excellent peak shape and good separation from water.

Injection: GSV (gas sampling valve);
Detection: PDD (Pulsed Discharge Detector).   

ammonia percentage level

high % level detection

Due to the aggressive property of ammonia, detection of ammonia at high % level is challenging for the lifetime of the analyser. MicroGC’s based on MEMS technology are not suitable for this purpose. GAS CompactGC4.0  is a microGC based on proven GC technology with rigid injectors and detectors. Reliable analysis of high level ammonia is provided. The chromatogram shows 10% NH3. Note that high % H2S is also analysed. 

Injection: GSV (gas sampling valve)
Detection: TCD 


GAS – Solutions for Energy, Refinery, Chemical and Environmental markets

Turnkey ammonia analyser by our company

Renewable energy is playing an increasingly important role worldwide. The GAS ammonia analyser offers accurate low and high level analysis of ammonia. Renewable energy is the backbone of a sustainable, CO2­-free energy sector, and thus a key technology for achieving decarbonization by the year 2100. Its share in global power generation is growing daily. GAS offers a range of solutions for analysis on catalysis and CO2 reduction, including ammonia and hydrogen fuel purity analysers.

Mass Spectrometer detection 

Mass Spectrometer detection can be used as an alternative to PDD, offering simultaneous detection at ppb level of other component groups. We are happy to inform you about the options we provide, like a diesel analyser. The ammonia analyser is just one example of what we have to offer. Browse our natural gas analyser or refinery gas analyser also.
