Title (EN) ATMOSPHERIC-PRESSURE IONIZATION AND FRAGMENTATION OF MOLECULES FOR STRUCTURAL ELUCIDATION
(FR) IONISATION ET FRAGMENTATION DE MOLÉCULES À PRESSION ATMOSPHÉRIQUE POUR ÉLUCIDATION STRUCTURALE
Abstract:
(EN) A solution-cathode glow discharge (SCGD) spectrometry apparatus may comprise an SCGD source and a mass or ion mobility spectrometer. A method for ionizing a molecular analyte may comprise contacting the molecular analyte with a plasma discharge to form ions and separating the ions in a mass spectrometer or ion mobility spectrometer. The contacting step may occur under atmospheric pressure and/or ambient conditions. The molecular analyte may be fragmented by the plasma discharge.
(FR) L'invention concerne un appareil de spectrométrie à décharge luminescente à solution-cathode (SCGD) qui peut comprendre une source de SCGD et un spectromètre de masse ou de mobilité ionique. L'invention concerne également un procédé d'ionisation d'un analyte moléculaire, qui peut consister à mettre l'analyte moléculaire en contact avec une décharge plasmatique pour former des ions, et à séparer les ions dans un spectromètre de masse ou un spectromètre de mobilité ionique. L'étape de mise en contact peut se dérouler à pression atmosphérique et/ou dans des conditions ambiantes. L'analyte moléculaire peut être fragmenté par la décharge plasmatique.
