Checking Gas Lines for Leaks
Regularly leak check each gas line from the gas supply in the laboratory
to the instrument.
❖
To perform a leak check for a gas line
1. After closing all valves in the instrument, monitor the manometer of
the gas regulator for some minutes.
2. If the pressure falls significantly (for example, the argon pressure falls
by more than 10 psi / 690 mbar within two minutes), you should
search for leaks in the gas line.
3. Search for leaks in the gas line (for example, by using a conventional
thermal conductivity-based leak detector, such as is widely used to
check leaks in gas chromatography equipment).
4. If you detect a leak (which is usually at a connection), verify the
tightness of the connection. In case of doubt, replace it.
5. When you cannot find a leak in the gas line, we recommend calling
a Thermo Fisher Scientific field service engineer to check for gas
leaks within the instrument.
