Popis: An automated method for the determination of arsenic acid (AsV), arsenous acid (AsIII), monomethylarsonic acid (MMAA) and dimethylarsinic acid (DMAA) was developed using a commercial available flow injection hydride generation system. By carrying out the hydride generation in selected acid media the determination of As(III) alone, of MMAA and DMAA by sum and by different sensitivities, and of all four species is possible.
