An analytical method for the relative concentration of trace elements in plasma protein by gel chromatog-raphy combined with SRXRF (Synchrotron Radiation X-ray Fluorescence) was developed. The relative concentration of trace elements was obtained using the normalized Compton scattering intensity of protein in X-ray spectra as a function of protein mass. The male Kunming mice were treated with and without cisplatin. The relative change of elements (Pt

Br and Sr) contents in the fraction of the plasma proteins (>22kD) of the mice were obtained. The determination prove that the element Pt in plasma is bound with macro-molecular protein
and that Cu and S are increased while Zn is decrease in the fraction of the protein in mice treated with cisplatin.
