Diffusive Sampling

Applications & Methods

Applications/Compounds that can be sampled with radiello


Typical applications include:
  • Ambient/Outdoor Air Monitoring (shown here with use of the radiello shelter)
  • Industrial & Indoor Air Quality (IAQ)
  • Industrial hygiene / Personal Sampling


radiello diffusive samplers have been designed for the following air-borne contaminants:

radiello and official methods, studies and projects

radiello or radial diffusive samplers are mentioned in following official methods:

EN 14412:2004 Indoor air quality- Diffusive samplers for the determination of concentrations of gases and vapours – Guide for selection, use and maintenance, (describes a radial sampler in general)
EN 14662-5:2005 Ambient air quality – Standard method for measurement of benzene concentrations – Part 5: Diffusive sampling followed by solvent desorption and GC; (describes radiello as type B sampler)
ISO/FDIS 16200-2 Workplace air quality – Sampling and analysis of VOCs by solvent desorption/gas chromatography – Part 2: Diffusive Sampling Method; (describes radiello as type D sampler)

 

More methods are dealing with diffusive sampling and are amendable to radiello. For a more extensive list, please see the reference list on radiello sampler


Studies
In recent years, the European Reference Laboratory for Air Pollution (ERLAP) has conducted numerous studies using radiello technology. Examples include: Validation of radiello Diffusive Sampler for Monitoring Ozone in Ambient Air (EUR 19594 EN), Laboratory and Field Inter-comparisons of NO2 diffusive samplers (EUR 20860 EN), and Laboratory and Field Inter-comparison of O3 diffusive samplers (EUR 21754 EN).

Projects
radiello samplers were used in the MACBETH project (Monitoring of Atmospheric Concentrations of Benzene in European Towns and Homes, LIFE 96 ENV/IT/070), the RESOLUTION project (Development of a high spatial resolution atmospheric monitoring model to verify the actual emissions reduction of ozone precursors foreseen by Auto-Oil program, LIFE99ENV/IT/081) and the ARTEMIDE Project (High temporal resolution monitoring of VOC's by diffusive sampler, LIFE 00 ENV/IT/000005) funded by the European commission's LIFE program for environmental projects. The later was recognized as one of 24 of the best LIFE projects in 2004/2005.
