This document describes the components of FT-IR monitors and is intended to provide guidance forthe FT-IR operator in field monitoring applications. A brief discussion of the FT-IR open-path monitor and its function is given in Chapter 2, along with a more in-depth description of the various components of the sensor. Chapter 3 includes the preliminary procedures for setting up the FT-IR instrumentation for monitoring. Chapter 4 is a discussion of background spectra, and Chapter 5 is a discussion of water vapor spectra. Chapter 6 presents guidance on how to set up the monitoring instruments within the physical constraints of a site. Chapter 7 presents experimental data that illustrate the effect of resolution and related parameters on the spectral data. Chapter 8 contains quality control and quality assurance guidelines, incorporating portions of an approved quality assurance plan, and includes selected QA data we collected over a recent one-year period.
