The aspects of the development and certification of the chromatographic strontium separation method in biogenic apatite samples for the subsequent 87Sr/86Sr isotopic ratio determination using multicollector inductively coupled plasma mass-spectroscopy are considered. The procedure for optimizing the Sr separation from matrix elements using standard chromatographic columns and SR Resin was described. The influence of matrix elements such as Na, Mg, P, Ca, Fe, Rb, Pb, Zn, In, K, Mn, Al, Ba on the 87Sr/86Sr isotopic ratio measurement was studied and the limits of their contents at which the separation procedure should be performed twice were estimated.
