Performing a Leak Test

Catalyst Activation

Thermo Scientific
Note Because the methanizer is not polarized, it is indifferent to which ports you
connect the inlet and outlet tubings.
8. Before reinserting the methanizer into the heating block, perform a leak test. See
"Performing a Leak Test"
9. At the end of the leak test, carefully reinsert the methanizer into the heating block and
close it by using the four fixing screws.
10. Reinstall the front panel and the cover of the methanizer assembly.
11. Reinstall and fix the protective grid.
12. Restart the GC and the TRACE 1310 Auxiliary Oven.
13. Activate the catalyst. See
 To perform a leak test
1. Turn on the hydrogen flow.
2. Check the metal tube connections with a handheld electronic leak detector to find
possible leaks.
IMPORTANT Perform the activation of the catalyst when the methanizer is installed the
first time, and when the methanizer temperature, the flow of hydrogen, or both remain off
for a period of time.

To activate the catalyst
Before starting this procedure do the following:
• Turn off the flame of the FID.
• Set the required carrier gas flow rate (helium or nitrogen).
• Set the injector temperature to 100 °C.
• Set the column oven temperature to 40 °C.
• Set the detector temperature to 250 °C.
