| For preliminary assessment and supplementary measurements it may be necessary to add simpler and less expensive sampling equipment. To establish the capability of performing screening studies using passive samplers or to verify potential highly polluted areas it is recommended that the central Reference laboratory will be equipped with adequate instruments for the analyses of filter samples and samples of SO2 and NO2.
This laboratory should at least have:
Ion
Chromatograph(s)
Atomic Absorption Spectrometer
Micro balances
Climatised room
The field equipment should include a number of passive samplers (including training procedures for impregnation and preparation of filters). This will establish the capability for indicative measurements and screening studies. Also a few sequential samplers for continuous 24-hour sampling of SO2 and NO2 will increase the possibility for evaluating the concentration distributions and verify dispersion models. These samplers are not considered reference instruments but will add to the value and quality of monitoring programmes.
All objects described above are integrated in a map and menu oriented user-friendly interface with direct link to the databases for measurements, emissions, modelling results and presentation tools. Advanced import/export wizards allow the user to transfer data easily to and from the AirQUIS system
