| Popis: | Document Type : Proceedings Paper Conference Date : JUN 21-25, 2011 Conference Location : Belgrade, SERBIA Conference Sponsor : Univ Belgrade, Inst Phys, Serbian Acad Sci & Arts (SASA), Republ Serbia, Minist Educ & Sci, Serbian Phys Soc, Serv Cooperat dact culturelle Ambassade France Serbie, Osterreichisches Kulturforum Belgrad; International audience; We report here the first coupling of an atmospheric pressure photoionization (APPI) source with a synchrotron radiation beamline in the vacuum ultra-violet (VUV). A commercial APPI source of a QStar Pulsar i from Sciex was modified to receive photons from the DISCO beamline at the SOLEIL synchrotron radiation facility. Photons are delivered at atmospheric pressure in the 4-20 eV range. The advantages of this new set up, termed SR-APPI, over classical APPI are spectral purity and continuous tunability. The technique may also be used to perform tunable photoionization mass spectrometry on fragile compounds difficult to vaporize by classical methods. (C) 2011 Elsevier B.V. All rights reserved. |
