Connecting the Gases
To Connect Both Argon and a Special Gas
Refer to the figure on page page 116 when you connect the furnace gases.
1. Make sure that the gas supplies are turned off.
2. Use the special tube cutter to cut the special gas tube into two pieces for the
two gas supplies. The ends of the tubes must be cut squarely.
3. Connect the gas tubes to the argon (or nitrogen) and special gas pressure
regulators. Use the R ¼'' screw connectors provided or use a connector or
adapter suitable for the gas regulator. Make sure that all the connections are
secure.
4. Pass the gas tubes to the rear of the spectrometer. Make sure that they cannot
be damaged or strained.
5. Push the free ends of the gas supply tubes into the Normal Gas and Special Gas
connectors on the manifold as shown. Push the tubes into the connectors until
the tubes butt up to the end of the connector.
Note
To disconnect the gas tube from a connector: Carefully push the black
locking ring of the connector into the connector and pull the tube out of the
connector.
