NIOSH, OSHA and EPA rules involve use of adsorbent tubes for “active” sampling of many toxic chemicals present in the atmosphere or in the duct flows as gases and vapors. From the quantity of captured substance, and determined analytically, it is possible, knowing the total volume of aspirated air, to determinate the concentration present in the environment.
Adsorbenti “Tubes”, produced by AQUARIA, have been developed in compliance with D. Lgs. n. 81/08: the two ends are closed with airtight caps and therefore it is no longer necessary to break the vial before use but just remove the caps.
The caps are also useful to prevent accidental breakage of vials: if dropped their diameter, slightly larger than the diameter of the vial itself, is a good protection.
With the aid of practical extractor (provided), you can easily rotate the porous plugs (and extract them if needed) thus removing the substrate without breaking the vial. This will prevent accidental injuries and the shedding of glass.
The opening system also ensures a homogeneous and linear air inlet flow as the entry point prevents the development of possible turbulence
Fields of application:
- indoor air sampling
- outdoor air sampling
- emissions sampling
