PDMS with Volatile Organic Compounds

Part of the NATO ASI Series book series (NSSB, volume 269)

Abstract

So far, the interest of Plasma Desorption Mass Spectrometry (PDMS) is focused on non-volatile, often thermally labile organic compounds. The main advantage of PDMS is that it is accessible to substances that cannot be converted into the gas phase without dissociation as it is typically for compounds beyond mass number 1000. In the present work, we report about first results of studies where PDMS has been applied to frozen organic compounds that are liquid or gaseous at room temperature and that are generally easy to handle by other methods such as Electron Ionization (EI) or Chemical Ionization (CI) mass spectrometry. Our aim is to investigate:
  1. (a)

    the possibilities of this method in comparison to ordinary mass spectrometry,

     
  2. (b)

    the ion formation process by using simple low-mass compounds and two-component mixtures,

     
  3. (c)

    the behavior of ion formation during sublimation and temperature rise.
