Arsenic speciation: HPLC followed by ICP-MS or INAA Conference Paper

abstract

• Sensitivities for the measurement of four arsenic species, As III, AsV, monomethylarsonic acid (MMA) and dimethylarsinic acid (DMA), in environmental waters and rice extracts by a new neutron activation analysis (NAA) method using pre-separation of the species by liquid chromatography were determined. A manual fraction collection was used to isolate the species, followed by instrumental neutron activation analysis procedures. The sensitivities determined for arsenic species in the samples varied from 1.21 to 1.47 ng per vial or about 30 gL-1 in sample solutions which translates to about 900 ng arsenic per gram of rice for our HPLC-NAA experiments. 2008 Springer Science+Business Media, LLC.
