    Author: Hou S, Chang C.
    Journal: Guang Pu Xue Yu Guang Pu Fen Xi; 2000 Jun; 20(3):364-7. PubMed ID: 12958958.
    Abstract:
    A method of loading a slurry prepared from a solid sample for analysis of chromium in geological samples using graphite furnace atomic absorption spectrometry had been approached by combining slurry sampling with probe atomization. The factors that influence the performances of chromium including ashing and atomization temperature, atomization surfaces were investigated. The results showed that the determination of chromium in geological samples could be performed by direct slurry sampling with the use of a calibration established with aqueous standards. The relative standard deviations(RSD) of the method were 3.0%-6.5%. The detection limit was 5.1 x 10(-12) g Cr. The Analytical results of the geological reference samples were consistent with the certified values.
