“…Additionally, the stability of iSb III during sample treatment may also cause problems. The development of an analytical methodology for the separation of the Sb species of NMG-Sb V , iSb V , and iSb III in Glucantime which overcomes these issues has been reported by Roldan et al 36 The revised method used anion exchange HPLC-HG-AFS in gradient elution mode with different concentrations of Na 2 H 2 EDTA as the mobile phase. The best results were obtained with a 1.20 min elution of 0.473 mmol L −1 Na 2 H 2 EDTA as the first mobile phase for the separation of NMG-Sb V , which was then changed to 20 mmol L −1 for the elution of the iSb species.…”
