Zusammenfassung

Die Möglichkeiten und die Grenzen zur Trennung von Metall-PAN-Chelaten in Reversed-phase-Systemen durch HPLC und DC werden systematisch untersucht. Nur die Elemente Cu, Ni, Co oder Cu, Fe, Co sind trennbar. Alle anderen Metallkomplexe sind in RP-Systemen instabil. Die optimalen Trennbedingungen sind: RP-2-Phase, mobile Phase: Acetonitril/Wasser/Citratpuffer pH 5 (80:18:2), 0,01M NH4SCN.

Summary

The possibilities for separation and the limits of detection of metal-PAN chelates in reversed-phase (RP) systems by HPLC and TLC are investigated systematically. Only Cu, Ni, Co or Cu, Fe, Co complexes are separable. All other metal complexes show instability in RP systems. The best conditions for separations are: RP-2 material, mobile phase: acetonitrile/water/citrate buffer pH 5, (80:18:2), 0.01M NH4SCN.
