In order to \ndetermine CO2 concentration and to develop simulation models, it is \nnecessary to carry out measurements which are accurate and comparable in \ntime and space, i.e. SI-traceable. Non-dispersive infrared (NDIR) \nanalysers are employed for CO2 measurements, as they are precise and \nstable. In order to achieve traceability, such instruments have to be \ncharacterized and calibrated. At the IMGC-CNR a procedure for calbrating \nNDIR analysers for CO2 at atmospheric level was developed, which enables \nto calculate a correction for the analyser output. In addition, a complete \nuncertainty analysis was carried out and a corrected traceability chain \nwas established. The goal of the present work is the study of the \nstability of a NDIR analyser by repeating calibrations during three years \nand comparing the correction curves obtained to identify a proper \ncalibration interval for such analysers. The investigated instrument has a \ngood repeatability and reproducibility, hence satisfactory stability \nduring time, as shown by the short-term and long-term compatibility of \ncalibration curves." ; prodottidellaricerca:prodottoDi istituto:CDS056 . ns9:ID574088 pubblicazioni:rivistaDi prodotto:ID6160 .
