radiello Parts and Components
The essential parts of radiello are the adsorbing cartridge, the diffusive body, and the supporting plate with the bar code indication. Apart from the adsorbing cartridge, all of the other components can be used multiple times.
The adsorbing cartridges for thermo desorption can also be reused. |
|
|
 |
(1) Open the plastic bag, draw the adsorbent cartridge out from the tube and put it in the diffusive body. The lower part of the diffusive body holds a seat for the central positioning of the cartridge (see right). The cartridge must be inserted fully into the diffusive body. |
|
|
 |
(2) Keeping the diffusive body in a vertical position, screw it onto the supporting plate |
|
 |
(3) Keep note of start date and time and insert the barcode label in the pocket without peeling it off |
|
 |
(4) Place assembled device on worker or location to be monitored. Keep note of the date and time and expose radiello .

(5) Keep note of the date and time of the end of exposure. Place the cartridge into the tube, peel off the label and stick it onto the tube such that the barcode is parallel to the axis of the tube. Forward the tube with the adsorber cartridge to the lab for analysis. |
|
 |
(6) Analytes are desorbed from the radiello tube using either solvent desorption (CS2, CH3CN, etc.) or thermal desorption. Spent cartridges are discarded. (Thermal desorption cartridges can be reused.) |
|
Complete analytical protocols for each analyte class are supplied in the radiello Manual.
