Thermo 42iTL (NO, NO2)

Gli ossidi di azoto (NOx=NO+NO2) sono misurati utilizzando un analizzatore a chemioluminescenza (Thermo 42i-TL), dotato di convertitore al molibdeno per la determinazione della NO2. A regime, ogni 24 ore viene eseguito un controllo di zero per la NO usando un generatore di aria zero e diluendo una miscela certificata di NO. In futuro la tecnica della GPT verrà utilizzata per verificare l’efficienza del convertitore di NO2.

Instrument (Thermo 42iTL) is connected by a Teflon pipe (OD: ¼”) to the air intake manifold. Antiparticulate filter (Teflon material) are present at the instrument inlet (changed every 30 days).

Currently only zero check are performed at the station by using an external zero air generator (Thermo 1160). A gas dilution/GPT system is available at the station (Thermo 160i). Once the implementation phase will be ended, this system will be used for executing every 48h span and zero checks for NO, as well as GPT test for evaluating the NO2 -> NO converter efficiency. A substitution of the analyser Molybdenum converter with a photolytic converter (e.g. BLC) is foreseen.

Data are recorded on a 1-minute basis by a station server and delivered in NRT mode to ISAC-CNR HQs in Bologna for publication on the web (http://www.i-amica.it/i-amica/?page_id=868).

Information about instrument functioning and intervention are stored within an e-logbook. Instrument manual are present at the station.

SOP are extracted by the ACTRIS “Draft for standardized operating procedures (SOPs) for NOxy measurements (Version: 2012/04/02)”
