General description

A radiello is basically a radial symmetry diffusive sampler.
The diffusive bodies are designed to house Radiello cartridge adsorbents during sampling. The diffusive bodies are threaded at one end for easy attachment to the Radiello triangular support plate. Unlike most of the cartridge adsorbents, the diffusive bodies are reusable and can be cleaned with a mild detergent between use. The diffusive bodies will collect dust (especially during outdoor sampling) and replacement is recommended after 4-5 uses.

Dimensions are 60 mm height x 16 mm diameter. There are four different diffusive bodies available. Each of which are application specific in design.


A radiello diffusive sampler may be used for thermal desorption during passive sampling, in an comparative study done to evaluate the relative performance of active and passive sampling methods in order to analyse the volatile organic compounds (VOCs) in ambient air. A radiello cartridge packed with Carbograph 4 may also be used in diffusive sampling to determine time-weighted average volatile organic compound (VOC) concentration in occupational hygiene and environmental air monitoring. A radiello diffusive sampler may also be used to monitor the cadaveric VOCs released by decomposing pig carcasses in three biotopes (crop field, forest, urban site).

The adsorbing cartridge is formed by a micropore polyethylene tube filled with silica gel coated with 4,4’-dipyridylethylene and closed, at one end, by a PTFE cap. Upon exposure, acid-catalysed ozonolysis of 4,4’-dipyridylethylene leads to 4-pyridylaldehyde.
