Changing Gases
Guidelines for Connecting Gases to the Analyzer
Use these guidelines when installing regulators and gas lines:
• Ensure that all gases needed are available and near the instrument. If the gas bottles are not located
near the instrument, you will have to use gas line extenders, which may degrade gas quality and
reduce pressure.
• Carefully route the gas lines from the bottle to the analyzer, avoiding overlapping or entangling gas
lines. This will ensure the correct gas pressure and make maintenance easier.
• Label both ends of the gas lines before connecting for ease in identification and maintenance.
• Ensure that all gas bottles are closed before connecting them to the analyzer.
The instructions below describe a typical installation. Some configurations require additional compo-
nents, such as regulator expansion kits, when one gas source will be used for several operations or
when the gas bottle cannot be located close to the analyzer.
Connecting a Gas Regulator to the Gas Supply
1. Attach an appropriate dual-stage regulator to the gas supply bottle or gas line you want to connect
and tighten with a wrench. Leave the gas bottle shut-off valve closed until instructed otherwise.
Dual-stage regulators must be used for all gas supplies.
If an expansion kit is required, attach it to the regulator before
proceeding. (Refer to the instructions included in the expansion
kit.)
