Zusammenfassung
Das beschriebene Verfahren zur Korrektur des Einflusses störender Begleitionen beruht auf dem Gebrauch von „Fehlerkurven“, die das Ausmaß der verstärkenden oder schwächenden Wirkung von Fremdionen angeben. Die flammenphotometrische Kaliumbestimmung in Gegenwart großer Mengen Natrium dient als Beispiel.
Summary
A procedure for correcting interferences in emission spectroscopy is suggested. It is based on the use of “error curves”, which are a measure of the extent of the enhancing (or suppressing) effect of the interfering element upon the sought-for one. The flame-photometric determination of potassium in the presence of large amounts of sodium is described as an example.
