Does FT-IR comparasion really give an accurate "fingerprint" of a material
 such as a two component epoxy such that the FT-IR results could be used
as
 a stand alone quality verification of the material?
Example:
We identify a specific batch of coating that has the desired properties we
want a manufacturer to reproduce from batch to batch.  We have the initial
batch "fingerprinted" by FT-IR and use that spectra as the "master
fingerprint" to which all subsequent batches are examined by FT-IR and
compared to the master.  If the spectra is "reasonably identical", does
that alone assure us that the coating is really the same as the master
batch?  Are there other lab tests that would give us a higher degree of
confidence?
Thank you very much!
