FTIR Spectrometer with Optical Filter for Low Level Gas Detection such as Formaldehyde and Ethylene Oxide

A gas analysis system with an FTIR spectrometer preferably utilizes a long path gas cell, a narrow band detector, and an optical filter that narrows the detection region. The interferograms are further prevent baseline drift and analyze the resultant spectra.
