Guidelines for Connecting Gases to the Analyzer

Guidelines when installing regulators and gas lines:
• Place gas bottles close to the analyzer. Using gas line extenders on gas bottles located in remote
areas may degrade gas quality and reduce pressure.
• Use a retaining strap (or other appropriate tether) to secure the gas bottle.
• Carefully route the gas lines from the bottle to the analyzer avoiding overlapping or entangling gas
lines.
• Label the gas line at the instrument inlet for proper identification and maintenance.
• Ensure the gas bottle is closed before connecting to the analyzer.
The following instructions describe a typical installation. Some configurations require additional com-
ponents, for example, 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.
In order to use oxygen, the analyzer must be equipped with an oxygen-compatible
vacuum pump that uses Fomblin
Failure to use the proper vacuum system could result in hazardous conditions
including fire and personal injury.
