Fig. 1From: Quantitation and speciation of inorganic arsenic in a biological sample by capillary ion chromatography combined with inductively coupled plasma mass spectrometryChromatograms of Arsenic species. a The chromatogram of the mixture solution (red) and the sum of the chromatograms in (b–e) (blue), and the chromatograms of the standard solutions of b MMA, c DMA, d As(III), and e As(V). In the mixture solution, the concentrations of As from each species were equally set to 5 μg/kg. Each standard solution contained 5 μg/kg of arsenicBack to article page
