General description

A radiello^™ diffusive sampler consists of 3 parts: the diffusive body, the adsorbent tube, and the triangular support plate. For personal air sampling, a vertical adapter can be installed. The adsorbent cartridge is removed from its glass or plastic storage tube and is inserted into the diffusive body. This is then threaded onto the triangular support plate in order to place the sampler in its sampling position.

Several different Radiello cartridge adsorbents are available. Each of which are specific for sampling different classes of compounds. The dimensions for each cartridge are 60 mm L x 4.8 or 5.8 mm D. Each cartridge is designed for one time use with the exception of Radiello thermal desorption (TD) cartridge adsorbents.

Each cartridge arrives in a sealed glass or plastic tube wrapped in a transparent thermally sealed polyethylene (PE) bag. The same sealed tube can be used to store the cartridge after sampling prior to desorption/analysis. A sufficient number of adhesive barcode labels are included with every pack of cartridges for easy tracking of sampling date and time.

Note: To conduct air sampling using the Radiello system, Radiello diffusive bodies and triangular support plates must be ordered (separately) in addition to cartridge adsorbents. Radiello Starter Kits (RADxxxS) include all the necessary parts to complete a sampling.

Application

A radiello^™ cartridge adsorbent packed with carbograph 4 along with PerkinElmer^® tube-type adsorbent packed with Tenax^® TA may be used in diffusive sampling in a study, done in order to measure the sampling rate variation of four different samplers namely GABIE, 3M 3500, PerkinElmer^® TA and radiello^™ 145 diffusive samplers, while being exposed to a low concentration of volatile organic compounds (VOCs) for a long duration (1-14 days).
