Replacing The Filling Materials - Thermo Scientific EA IsoLink IRMS System Operating Manual

Replacing the Filling Materials

The replacement of reactors and adsorption filters requires the replacement of their filling materials.
This operation comprises two steps. Alternatively, prepacked reactors can be obtained via your local
Thermo Fisher Scientific Office.
• Removing the exhausted filling material from the reactor.
• Restoring the sequence of the layers of filling materials using new reagents.
Perform these operations according to the instructions given in the following operating sequences.
• "To replace the filling material in quartz reactors"
• "To replace the filling material in adsorption filters"
 To replace the filling material in quartz reactors
Material required
Tool for cleaning quartz reactors P/N 27606010 (included in the Standard Outfit of all
EA IsoLink IRMS System for CNSOH Configurations)
Filling materials depending on analytical setup. Consult the CookBook for different reactor
setups.
CAUTION Before starting the operation, check that the furnaces are at room temperature.
Remove the quartz reactor from the furnace, then do the following:
1. Introduce the cleaning tool into the reactor as shown in
Figure 134. Removing the Filling Material from a Quartz Reactor
2. Rotate the tool exerting a slight pressure to scrape off the filling material.
3. Collect the removed filling material as shown in
4. Repeat steps 1 and 2 until complete elimination of the exhausted filling materials.
