Short summary
LNE developed, with the company 2M PROCESS, a gas reference generator to dynamically generate NH3 reference gas mixtures in the air at very low fractions between 1 and 400 nmol/mol. The procedure defined by LNE for calibrating NH3 analyzers used for monitoring air quality guarantees relative expanded uncertainties lower than 2 % for this measurement range. The results of a comparison organized between METAS and LNE allowed the validation of LNE's reference generator and calibration procedure.
