  • Title: Applications of diamond crystal ATR FTIR spectroscopy to the characterization of ambers.
    Author: Guiliano M, Asia L, Onoratini G, Mille G.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2007 Aug; 67(5):1407-11. PubMed ID: 17129753.
    Abstract:
    Diamond crystal ATR FTIR spectroscopy is a rapid technique with virtually no sample preparation which requires small sample amounts and showed potential in the study of ambers. FTIR spectra of ambers present discriminating patterns and can be used to distinguish amber from immature resins as copal, to determine local or Baltic origin of archaeological ambers and to detect most of the falsifications encountered in the amber commercialisation.
