| Popis: | A transportable FT-ICR/MS associated with a flowing atmospheric pressure afterglow ionization source has been developed for air monitoring applications with the objective of detecting organic compounds with both a good mass resolution and a good sensitivity. The main features of the apparatus and its operation mode are described. The glow discharge source is operated with helium at atmospheric pressure. Excited helium species react with air and the ionic products formed are sent in the mass spectrometer within a gas pulse. They are intercepted using a hexapole trap before being sent to the ICR cell located in a differentially pumped chamber for mass analysis. The permanent magnet assembly generates an axial field, thus enabling ion transfer from an external source. FT-ICR detection with this configuration is characterized both for internal and external ionization. First results obtained for the detection of several polycyclic aromatic hydrocarbons (naphthalene, acenaphthene and acenaphthylene) are presented showing detection limits in the high ppb range, and a detection time of a few seconds. |
