IRGASON Integrated CO

O Open-

Path Gas Analyzer and 3D Sonic

Anemometer

1. Introduction

The IRGASON 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, Cautionary Statements

• Section 3, Initial Inspection

• Section 6, Installation

More details are available in the remaining sections.

2. Cautionary Statements

• DANGER:

o The scrubber bottles (see Section 9.5, Replacing Desiccant and

Scrubber Bottles) 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.
