O Open-
Path Gas Analyzer and 3D Sonic
Anemometer
1. Introduction
The IRGASON, U.S. Des. Patent No. D680455, is an in-situ, open-path, mid-
infrared absorption gas analyzer integrated with a three-dimensional sonic
anemometer. The gas analyzer provides measurements of absolute densities of
carbon dioxide and water vapor, while the sonic anemometer measures
orthogonal wind components.
Before using the IRGASON please study:
• Section 2 , Precautions
(p. 1)
• Section 3 , Initial Inspection
(p. 2)
•
Section 6 , Installation
(p. 7)
More details are available in the remaining sections.
2. Precautions
• DANGER:
o The scrubber bottles (see Section 9.5 , Replacing Desiccant and
Scrubber Bottles
(p. 32)
) contain the strong oxidizing agents
sodium hydroxide (caustic soda, NaOH) and anhydrous
magnesium perchlorate (Mg(ClO


Avoid direct contact with the chemicals.

Ensure your work area is well ventilated and free of
reactive compounds, including liquid water.

Store used chemical bottles in a sealed container until
disposal.

Dispose of chemicals and bottles properly.

Materials Safety Data Sheets (MSDS) are provided in
Appendix C . MSDS are updated periodically by
chemical manufacturers. Obtain current MSDS at

• WARNING:
o Do not carry the IRGASON by the arms or the strut between the
arms. Always hold it by the block, where the upper and lower
arms connect.
o Handle the IRGASON carefully. The optical source may be
damaged by rough handling, especially while the analyzer is
powered.
o
Over-tightening bolts will damage or deform the mounting
hardware.
•
CAUTION:
o
Grounding the EC100 measurement electronics is critical. Proper
grounding to earth (chassis) will ensure maximum ESD
(electrostatic discharge) protection and improve measurement
accuracy.
o
Do not connect or disconnect the gas analyzer or sonic connectors
while the EC100 is powered.
