Abstract: Measurements of characteristic masses for Ag, Cd, Cr, Ga, Ge and In have been made over broad temperature intervals.The experimental results show that the values of m0 have appeared to be better than 10% -15% when the analytes are atomized in temperature intervals studied.Influences of atomization temperatures on the ratio m0[cmlc.]/m0[exp.] were studied when the analytes were e-vaporated from the wall, using the platform and the V-shaped boat techniques.For Ag and Cd the ratio m0[cmlc.]/m0[exp.] does not change significantly in the temperature intervals studied.However, for the remaining four elements (Cr, Ga, Ge, In) the ratio m0[cmlc.]/m0[exp.] varies with temperature.The ratio m0[cmlc.]/m0[exp.] of In or Ge was increased obviously in the presence of matrix modifier.

Key words: Graphite furnace atomic absorption spectrometry, Characteristic mass.Atomization temperature, Matrix modifier
