Spark source mass spectrometry technology

The rapid development of mass spectrometric technology and the wide field of applications exclude a complete and comprehensive discussion of mass spectrometric possibilities for trace analysis of metals. Therefore, this report will give a brief outline of the principles of mass spectrometry (MS) and the fundamentals of qualitative and quantitative mass spectrometric analysis with emphasis on recent developments and results. The classical methods of analysis of solids, i.e. spark-source MS and thermal ionization MS, as well as newer methods of metal analysis are described. Focal points in this survey of recently developed techniques include secondary ion MS , laser probe MS , plasma ion source MS gas discharge MS and field desorption MS . Here, a more detailed description is given and the merits of these emerging methods are discussed more explicitly. In particular, the results of the FD techniques in elemental analyses are reviewed and critically evaluated.
