Field desorption mass spectrometry in the analysis of a steroid conjugate, estriol-16α-glucuronid
摘要：
Field desorption mass spectrometry was used for the first time in the analysis of a steroid conjugate, the estriol-16α-glucuronide, isolated from pregnancy urine. Two reference compounds were also investigated. The molecular ion peak of the underivatized conjugate was obtained indicating that the molecular weight of such compounds can easily be determined. Variation in the solvent composition causes some variation in the spectra obtained and complex ion formation was noted. Because of the ubiquity of sodium and potassium, ions containing these metallic elements and representing the sodium and potassium salts of the steroid glucuronic acid are seen in the spectra.
