|The TGA Vapor-Phase Library
contains 460 spectra of compounds most likely to evolve during TGA/FT-IR experiments.
Spectra of compounds in the library range from methane to hydrogen bromide, and from
acetaldehyde to p-xylene.
Spectral search results
from the TGA Vapor-Phase Library can be invaluable to R&D chemists studying both
composition and decompositional properties of materials. It is equally useful to QC
investigations when products do not meet specifications.
The majority of the spectra were acquired by Aldrich
Chemical Company using a Thermo Scientific FT-IR GC interface coupled to an HP 5790 Gas
Chromatograph. These spectra were supplemented by EPA spectra and by spectra acquired by
the Bayerische Julius Maximilian Universitat Wurzburg and Universitat Hannover.
While the TGA Vapor Phase Library will help
to identify most low molecular weight gases, there are of necessity fewer
vapor spectra of higher molecular weight. Those investigators who require a
database with spectra of more exotic species and combinations of functional
groups should consider obtaining the Nicolet
