Noticeable trends in inorganic mass spectrometry are speed, simultaneity, and fewer problems from isobars and tuned plasma conditions. Inorganic MS techniques used for inorganic trace analysis have been reviewed [350]. Various monographs deal with inorganic mass spectrometry [351,352] and plasma-source mass spectrometry in particular [353,354].

Inorganic trace analysis requires more than cursory attention to sample collection and treatment techniques since contamination is not only possible but often unavoidable. A good discussion of problems encountered in extreme trace analysis has been published by Tolg (99). The following section discusses some innovations in atmospheric and water sampling procedures. 

GC has been used extensively for the separation and determination of volatile organic molecules, and most aspects of this application area are fully documented in monographs on this technique. In the inorganic trace analysis area, however, fewer species possess the required volatility, and applications tend to be limited to the separation of volatile species of low molecular weight (such as methyl derivatives of As, Se, Sn, Hg) and the separation of semi-volatile organo-metals, metal halides, metal hydrides, metal carbonyls and metal chelates. For organo-metal species, the type of detection system required varies with the nature of the analyte, and the options include electron capture detection, flame photometric detection (sometimes ICP), AAS and MS.

Any CRM for chemical composition is suitable for the purpose of trace analysis if it is certified for trace constituents and minimum sample mass, which guarantees that the homogeneity of the material is appropriate for the analytical method used in a laboratory. Taking into account the matrix, it if often useful to distinguish the following main classes of reference materials for chemical composition for inorganic trace analysis ... 

A general strategy for preparation and certification of matrix CRMs for inorganic trace analysis adopted by INCT is presented in Table 4.4 [35, 36].
