Abstract:Summary The aim of every analytical experiment is to gain information about a particular chemical system. In order to design and carry out such an experiment it is necessary to take into consideration the chemical properties of the matter as well as the metrological rules inherent in the analytical method applied. In this aim (to obtain information) and in the manner of working (to regard chemical properties and metrological rules) analytical chemistry can be seen as being a uniform and independent scientific discipline. The different analytical methods and the numerous analytical problems can then be described in uniform manner. The different measuring parameters and steps in analytical work can all be reduced to uniform terms and processes. The treatment and evaluation of the signal produced in the analytical experiment is always at the centre of all discussions. The uniform theoretical interpretation of seemingly different methodological terms makes a standardized nomenclature possible. The aim of effectively obtained information explains the preference of certain analytical methods for trace analysis, structure analysis, multicomponent analysis or other analytical problems. Furthermore, it is possible to derive useful strategies for applying an analytical method or managing an analytical problem. Finally, tendencies can be shown for the development of analytical methods, which are particularly effective in obtaining information.
