What is Radiello Working News Bibliography Search About us Contacts IT Air quality monitoring with the original radial symmetry diffuse sampler Components The radial symmetry diffusive sampler What is radiello system for air quality monitoring? radiello is a sampling “system” for air quality monitoring that requires the use of several components to operate. The main components are: a supporting plate, a diffusive body, an adsorbing cartridge, a barcode label to make the sample traceable. With these few, but essential, elements your sampling will be successful. Virtues of air quality monitoring with Radiello® Air quality monitoring with the Radiello diffusive sampling does not involve the use of heavy and encumbering pumping systems, it does not have energy power supply problems, it does not require supervision, it is noiseless, not flammable and it does not present an explosion hazard. The diffusive sampling can be performed by anybody, anywhere, with very affordable costs. By virtue of radial symmetry, the uptake rate is: high, despite having the same dimensions, radiello’s uptake rate is at least three times higher than that of any axial diffusive sampler; constant, thanks to the great adsorbing capacity of the adsorbing substrates; reproducible, due to the continuous control of all the used materials’ homogeneity and the check of all the production lots of radiello; precisely measured, because the flow rate is not estimated but calculated experimentally, measured in a dynamic atmosphere controlled chamber in a wide range of conditions of concentration, temperature, humidity, air velocity, presence of interfering… Radiello's products Discover the complete range of radiello’s products: • Adsorbing and chemiadsorbing cartridges • Diffusive bodies • Supporting plates and adapters • Starter kits • Radiello-ready-to-use • Accessories and spare parts Components Methods Hydrochloridric acid Hydrofluoric acid Aldehydes Ammonia COV chemically desorbed COV thermally desorbed Phenols Anaesthetic gases Hydrogen sulphide NO2 e SO2 Ozone 1,3 - Butadiene and isoprene Visit the Maugeri website Scientific literature Radiello High uptake rate radial diffusive sampler suitable for both solvent and thermal desorption 1996 - Cocheo, V., Boaretto, C., Sacco P. A new diffusive sampler with radically changed diffusive path geometry was developed. The small cylinder has a height greater than its radius; the diffusive surface is the external cylindrical one, and the adsorber is a coaxial inner cylindrical cartridge. Due to the high value of diffusive area-path length ratio and to the high loading capacity… View Article Ambient volatile organic compounds monitoring by diffusive sampling. Compatibility of high uptake rate samplers with thermal desorption 1997 - Bates, M., Gonzalez-Flesca, N., Cocheo, V., Sokhi, R. Field and laboratory validation studies were carried out on a novel, high uptake rate, radial diffusive sampler loaded with Carbotrap, a thermally desorbable adsorbent. For field experiments parallel techniques were employed for comparison. The goal was to assess the compatibility of the device for subsequent thermal desorption and preconcentration of the sample for analysis.

Many VOC represent hazards to human health through chronic exposure. Recent European and world-wide legislation proposes limit values for ambient concentrations of these compounds. However, very little experimental data exists for true population exposure. In 1996, the European MACBETH initiative set out to measure population exposure to benzene in six European cities. This study details… View Article Archive Application notes Urban air quality monitoring at high spatial resolution by diffusive sampling. 15 July 2019 - Urban Air Quality High spatial resolution monitoring using diffusive samplers allows studying the urban pollutant distribution, thus enabling deeper investigation of their generation and diffusion mechanisms. Nevertheless, such a monitoring campaign has a certain cost. Aim of the note is to suggest how to realize a monitoring campaign of urban pollution by diffusive sampling at high spatial resolution…. View Article Occupational exposure assessment to chemical agents. 15 July 2019 - Occupational exposure In compliance with the provisions of the UNI EN 689 Standard for the assessment of occupational exposure to chemical agents personal samplings have to be privileged; these can be performed using systems placed in the respiratory zone of the operators as they are considered the most representative of the potential inhaled exposure. At the same… View Article Archive News Complete sampling with radiello 14 November 2019 Would you like to find out how to perform a complete sampling with radiello?
