The author has been active in developing techniques for analysis of solids, 

The question may be posed Is there any difference between analysis of rare earth matrices and other types of matrices by SSMS The answer is Generally, no . However, analysis of rare earth matrices may be handled as a group within which reliable techniques can be applied to improve confidence levels in determinations. In describing how these matrices may be handled, the author assumes that the reader is knowledgeable of current techniques in SSMS, instrumentation, detection limits, etc. either by having read the previous chapter or from other more general descriptions such as Ahearn (1972). 

It should be noted that only information, techniques, or trends are presented here which have been judged to be pertinent to the analysis of rare earth matrices by SSMS. Some of the contents may be considered typical of other elements or groups of elements and some contents are peculiar to rare earths. For any applicability of the contents described in this chapter to other matrices the reader is referred to more general references (Ahearn, 1%6, 1972).
