Abstract
An automatic analytical apparatus in which a series of operations ranging from the sampling into a treating receptacle, pretreatment, analysis and discharge of a fluid sample to the preparation for the next analysis are repeated automatically in order, wherein the time-dependent variation of the composition is traced successively. This permits the presence of the composition variation or the course of the composition variation to be confirmed or the composition variation to be controlled, automatically.
