A slurry sampling hydride generation method for As(III) and total inorganic As, without total sample digestion, has been developed using a continuous flow mode generation system coupled with atomic absorption spectrometric determination from environmental (marine sediment, soil, rock salt, waste water) and biological (human hair and urine, lobster, liver, muscle, beer and wort, tablets) samples. It involves trapping of the arsenic vapor on a pre-heated graphite furnace inner wall at 300 °C… CONTINUE READING
