Atomic spectrometry update. Advances in atomic emission, absorption and fluorescence spectrometry and related techniques

“…The simultaneous detection of As and Se in the dimethyldiselenoarsinate anion by HPLC-ICP-AES using Hamilton PRP X-100 resin and a phosphate based mobile phase has been described. 530 The authors propose that the compound forms from reactions of DMA with selenite and glutathione and, as such, it is possible that it could interfere with the determination of Se. The proposed method separated the anion from As(V), Se(IV), DMA, MMA and low molecular weight thiols (e.g., glutathione).…”
