Zusammenfassung

Es wurde die Software für eine Ensemblesummierung von Signalen bei der Injektionsdosierung von flüssigen Mikroproben in der Atomabsorptions-Spektroskopie entwickelt. Bei der Ensemblesummierung von 16 einzelnen Fällen (Injektionen) wird 4mal die Nachweisgrenze herabgesetzt, was auf Grund der Verbesserung der Reproduzierbarkeit erfolgt. Die Herabsetzung der Nachweisgrenze wird am Beispiel der Elemente Cd, Mn, Ni, Ag, Zn, Pb, Fe, Se und Na gezeigt.

Summary

The software for the ensemble summation of signals in atomic absorption spectroscopy combined with injection dosation of liquid microsamples is developed. The average of 16 realizations provides a 4-fold lowering of the detection limit of the elements as a result of improved reproducibility. The method is illustrated by the trace content determination of Cd, Mn, Ni, Ag, Zn, Fe, Se, Pb and Na.
