Analytical properties hierarchy

One key element of metrology is traceability of a measurement result to the Si-system ensuring comparable results. Traceability is defined as the property of the result related to national or international standards through an unbroken chain of comparisons all having stated uncertainties. The overall objective in the hierarchy of measurement procedures is dedicated to the highest available analytical quality. This principle is... 

Geerlings De Proft, 2008 Cardenas et al., 2009 Senet, 1996). One may obtain a condensed-to-atom variant and also for the electrophilic, nucleophilic and radical attacks in the usual way. Moreover, the inverse of tu(r,r ) may generate a hierarchy of nucleophilicity kernel. Unlike the previous formulations, the overall treatment here is general and analytic with hardly any bearing on the explicit form of E(N). The traditional operational definition of local softness and hardness contain the same potential information and they should be interpreted as the local abundance or concentration of their corresponding global properties. 

This double picture accounts for many of the issues which I have just described. Natural historical descriptive approaches could be used to indicate the range of desirable properties which a chemical substance might have this then allowed for the specification of precise analytical procedures to detect them and to allow decisions to be made about questions of chemical composition. For some chemical workers during the eighteenth century, it is quite clear, natural history which ordered materials according to their places of origin was a spur to develop new productive practices which could overturn existing hierarchies of value.
