Model ANALYST - Diffusive Sampler



ANALYST is a diffusive sampler to axial symmetry, of long period, therefore suitable for the determination of average concentrations of gas and steams in the urban atmosphere. The passive sampling exploits the capacity of many substances to spread in the atmosphere and to 'bind themselves' to suitable adsorbents. The diffusive sampler absorbs and keeps the substances, which are to be sampled.

The amount of polluting sampled is then determined with suitable quantitative analysis and his average concentration is determined knowing the sampling duration, the equivalent range and the mass (noticed analytically) of the polluting examined.

The (passive) diffusive sampling so does not require either the pump use or any source of energy, is a silent system, comfortable, of low dimensions and low cost and does not require the specialized staff’s intervention.

The technique of the passive sampling with ANALYSTr (patent RM 98A-000584) has been developed by the Institute On The Atmospheric Pollution Of The National Research Council, Rome, Italy.

Analyst is a ready to use sampler and is the first in compliance diffusive sampler to the rules of law: it is in fact equipped with equivalence certificate, as required by D.M. n° 60 of the April 2002 for the air good quality evaluation.
