A flow injection technique was applied to hydride-generation atomic absorption spectrometry. For the present reaction, gas segmentation was found to be effective in minimizing the broadening of a sample zone without an increase of noise levels. When 0.5 mL of samples was used, arsenic, antimony, bismuth, selenium, and tellurium could be determined with the detection limits (S/N = 3) of 0.04-0.3 ng and relative standard deviations better than 2.5%. About 120 samples could be determined within an hour. These elements in several NBS SRMs were determined.

Simultaneous determination of inorganic anions and cations by ion chromatography with EDTA (ethylenediaminetetraacetic acid) as eluent

Various decomposition methods were examined for the determination of 21 elements in atmospheric particulates. Alkali fusion with sodium carbonate and boric acid was selected for the determination of Si, Ti, Al, Fe, Mn, Mg, Ca, Ba and Cr, decomposition with HF-HNO3-HCl for Na, K, Pb, Zn, Cd, Co, Cu, Li, Ni and V and decomposition with HF-HNO3-H2SO4-KMnO4 for As and Sb. The determinations were carried out using hydride generation atomic absorption spectrometry for As and Sb, air-acetylene flame atomic absorption spectrometry for Cr, Ca, Co, Fe, Mg, Mn, Ni, K, Li, Na, Cd, Cu, Pb and Zn and dinitrogen oxide-acetylene flame atomic absorption spectrometry for the other elements. The performance of the recommended procedure was confirmed by analysing the National Bureau of Standards, Standard Reference Material 1648 Urban Particulate Matter. The recommended procedure was applied to the analysis of total atmospheric particulates and of particulates smaller than 10 µm.
