passam takes part in the measurement of ammonia in Scottland – Covered in Umwelttechnik Deutschland Schweiz
Excessive ammonia emissions are harmful to human health and ecosystems.
SI traceable measurement of the reactive gas in ambient air is therefore important but challenging.
The research work of the three-year MetNH3 project compared different approaches in laboratory and field studies. This improved above all the metrological traceability – not least due to the mobile reference gas generator ReGaS1.
