Preparing The Adsorption Filter - Thermo Scientific EA IsoLink IRMS System Operating Manual

Preparing the Adsorption Filter

The filling materials are introduced into the empty filter to form a series of layers of defined
dimensions. For a proper preparation of the layers, refer to the filling diagram of the concerned
instrument configuration, as described in the section
on page
The filling procedure should be carried out on a wide and clean workbench. See

 To fill the adsorption filter
The following procedure provides instructions for filling an adsorption filter.
Material required
Plexiglas filter
Compression rod
Filling materials
1. Introduce into either of the tube ends a sufficient amount of quartz wool to form the required layer
as shown in
Figure 47. Introduction of Quartz Wool into the Tube
Threaded End
2. While plugging the tube mouth with your hand, press gently the quartz wool using the rod
provided.
3. Screw the nut complete with its seal onto the threaded mouth, as shown in
Thermo Scientific

WARNING Before using the filling materials required for this operation, please read the
hazard warnings and information reported in the Material Safety Data Sheets (MSDS)
provided, referring to the relevant CAS (Chemical Abstract Service) number.
The filling of reactors requires the use of quartz wool. Before handling
quartz wool, we recommend to wear gloves and face protection.
Always use original Thermo Fisher Scientific materials and products. The use of materials
not meeting the technical specifications of our products does not ensure a good operation
of the instrument and may even damage it.
