Trace metal ions qualitative analysis

The present account brings together the themes which led to that first resolution of a purely inorganic compound, defined as containing no carbon of any kind. These themes are first, optic activity and its relation to stereochemistry second, an aspect of qualitative analysis related to the complexation of metal ions, and, finally, chelation in aqueous coordination chemistry. The paper concludes by tracing the development of inorganic optically active compounds since Werner s time. 

The chapter emphasizes the superior analytical power of ion chromatography so that it can be used for qualitative and quantitative analysis of common cations, anions and halides in their different forms and matrices in trace and ultra-trace concentrations. Heavy metals separation and detection was also mentioned as well as hydrogen cyanide as an example of inorganic... 

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.
