Analytical Chemistry and their mutual relationships. For details, see text
1.15) and the action of analysing (see Fig. 1. IS). Reports (viz. results discussed in
the light of the social-economic problem addressed) are the outputs of analysing
and should be consistent with quality outside the laboratory. Figure 7.4 shows
additional relationships that can be used to complete, in a global, integral
manner, the contents of Sect. 1.6.
The capital analytical property representativeness (see Sect. 2.4.2) is an essential ingredient of quality in the analytical information (see Fig. 7.1). At its
highest level, the results produced are fully consistent with the social-economic
problem, so the ensuing analytical problem will have been correctly solved
(third level in Fig. 2.8). Thus, properly solving the analytical problem entails
ensuring that the results are fully representative. The analytical problem is also
related to traceability of a sample aliquot (see Box 7.3).
