Zusammenfassung

Anreicherungsverfahren sind in der anorganischen Spurenanalyse unentbehrlich, um die Nachweisgrenzen zu verringern, Richtigkeit und Genauigkeit zu verbessern und den Anwendungsbereich instrumenteller Methoden zu erweitern. Diese kurze Übersicht behandelt die allgemeinen Gesichtspunkte, d. h. Kontrolle von Verunreinigungen und Verlusten, Anreicherung im Mikro- und Makrobereich, Multielement-Anreicherung, Anreicherung zur chemischen Speziation sowie Vereinfachung und Automatisierung der Verfahren.

Summary

Preliminary enrichment is indispensable for inorganic trace analysis, to lower the detection limits, improve the precision and accuracy, and widen the scope of instrumental determination techniques. This short review deals with the general aspects, which include control of contamination and losses, micro- and large scale enrichment, multielement enrichment, enrichment for chemical speciation, and simplification and automation of the techniques.
