As the price and detection limits of FT-IR instrumentation decrease the technique is receiving renewed interest as a method of measuring organic vapors in air. We will describe the results of several recent experiments we have performed in using FT-IR to monitor ambient air. We will also discuss several options that are available to make these measurements. As part of this paper we will report detection limits and how they apply to real world samples consisting of complex mixtures of organic materials.
