1.1 Analysis method life cycle
An analytical method is a procedure, i.e. a series of more or less complex, programmed operations, the aim of which is to determine an analyte. If we stick to strict metrological vocabulary, we should speak of measurand, rather than analyte. However, analysts have been able to gain acceptance for the latter term, which is better suited to their discipline.

As most analytes are difficult to relate to a standard in the International System (SI) of units, the initial question for an analyst is to ensure that what he or she is measuring corresponds...
