The analysis of solid materials by introducing solid test sampies
directly into the graphite furnace of an atomic absorption
spectrometer must be regarded as a powerful analytical approach.
Even if it is - of course - not the "ultimate method." After three
decades of development, the instrumentation and the methodology are
available to apply solid sampling successfully for the analysis of
almost every material. Moreover, several tasks cannot be solved
using other analytical methods as neatly as they can using direct
solid sampling. The conventional methods work more or less
satisfactorily, so why do we sug gest applying solid sampling much
more extensively than it is today? To begin with, the features
pointed out time and again should be named: Rapidity of the
analytical procedure, low susceptibility to analyte loss or
contamination, very smallquantities can be analyzed, and
expenditure on instrumentation and per sonell is also low. These
properties are examined and the necessary conditions are discussed
(Chapter 1) as are the analytical tasks (Chapter 6) for which use
of this method is advantageous. Other features that are often
overlooked are just as important: The simplicity of the analytical
procedures allows the analyst to main tain an intimate relationship
with the original scientific task that has to be solved with the
analysis. Furthermore, the considerable reduction of working place
haz ards and pollution by avoiding the use of chemical reagents
must nowadays be assessed as a feature as important as the others."
