Il limite di rilevabilità dello strumento è pari a 0.05 ppb (medie sul minuto). In futuro la tecnica della GPT verrà utilizzata per verificare l’efficienza del convertitore di NO2. Instrument (Thermo 42TL) 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). Detection limit was assessed to be 0.05 ppb. No dilution system (for NO span) nor GPT system (for NO2 calibration) are currently available at the station but actions are currently on-going to obtain funds for installing these devices. Also the substitution of the analyser Molybdenum converter with a photolytic converter 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. Information about instrument functioning and intervention are stored within an e-logbook. Instrument manual are present at the station. NOTE: substitution of the Mo converter by a photolytic converter (e.g. BLC) is foreseen. Actions are currently on-going to achieve this objective.

You can add and remove fields and fill out default information (e.g. contact details). Fields you can not change in the default view may be accessible in the more comprehensive (and more complex) advanced view. You can even use the XML editor to create custom structures, but they have to be validated by the system, so know what you do :-) http://www.i-amica.it/i-amica/?page_id=632 WWW:LINK-1.0-http--link Site description http://www.i-amica.it/i-amica/?page_id=1125&lang=en Real time data OGC:WMS-1.1.1-http-get-map
