A new application of high resolution continuum source flame atomic absorption spectrometry has been developed for the determination of Ca, Fe, Zn and Mn in chicken feed. Under the selected determination conditions, the correlation coefficients better than 0.998, the relative standard deviations less than 2.6% and the recoveries between 96.3% and 103.1% were obtained for the four metal elements. The characteristic concentrations were 0.092 mg/L (Ca), 0.17 mg/L (Fe), 0.033 mg/L (Zn) and 0.15 mg/L (Mn), respectively. The results showed that the contents in chicken feed were 6.75±0.12 mg/g (Ca), 1.30±0.03 mg/g (Fe), 0.174±0.05 mg/g (Zn) and 0.313±0.04 mg/g (Mn), respectively. Therefore, the proposed method was accurate and stable with a high practical value. It provided scientific basis for determination of metal elements in food
