Choosing the right background measurement can make or break the reliability of FTIR gas analysis.
Ambient air is often convenient, but is it always the best option?
Or does nitrogen provide a more controlled and reliable background?
In this article, we break down how to choose the right background measurement based on real measurement conditions, not theory alone.
➡️ You’ll learn how factors like
• gases already present in ambient air
• moisture and temperature conditions
• timing and on-site practicality
affect measurement accuracy and guide the choice between ambient air and nitrogen.
