  • Title: Fast atom bombardment mass spectrometry of estrogen glucuronides and sulfates.
    Author: Liehr JG, Beckner CF, Ballatore AM, Caprioli RM.
    Journal: Steroids; 1982 Jun; 39(6):599-605. PubMed ID: 6297126.
    Abstract:
    Fast atom bombardment (FAB) mass spectra of 13 intact, underivatized glucuronides and/or sulfate salts are reported. Spectra are characterized by abundant ions formed by attachment of a proton, [M+H]+, or of an alkali ion, [M+alkali]+, to the glucuronide or sulfate salt. Fragment ions were of low intensity. FAB spectra can be used to obtain the molecular weight of a sample, to assess its purity and to identify the nature of the alkali of the glucuronide or sulfate salt.
