What is FT-IR?

    FT-IR is an abbreviation for Fourier Transform - Infrared.  It is an analytical technique for qualitatively and quantitatively determining the molecular composition of a solid, liquid, or gaseous sample.  If that technical definition doesn't mean much to you or even if it does but you want to know more, we've created an online "FT-IR Primer" just for you.  Our FT-IR Primer should help just about anybody understand the basics of infrared spectroscopy, even our non-technical visitors who aren't afraid of a little physics and chemistry.  Our Primer explains all of the scientific concepts upon which FT-IR depends and we've tried to do it in layman's terms, as much as possible.  This full-blown explanation also explains the "Fourier Transform" part of FT-IR, which may be of interest to some of our more technical visitors as well. 

For our visitors who basically understand FT-IR spectroscopy but are interested in it's open-path air monitoring capabilities, we have a few pages that attempt to explain both active and passive open-path FT-IR techniques.
