Vol. 76, No. 6, pp. 1215–1225 (2004) Calibration in analytical chemistry refers to the relation between sample domain and measurement domain (signal domain) expressed by an analytical function x = fs(Q) representing a pattern of chemical species Q and their amounts or concentrations x in a given test sample on the one hand and a measured function y = f(z) that may be a spectrum, chromatogram, etc.

Relationship between sample domain and signal domain in case of elemental analysis. |
Simultaneous multispecies analyses are carried out mainly by spectroscopic and chromatographic methods in a more or less selective way. For the determination of n species Qi (i = 1,2 …n), at least n signals must be measured which should be well separated in the ideal case. In analytical practice, the situation can be different.
