Procedure was proposed for the radiochemical neutron activation analysis of the Kara astrobleme geological samples using a Purolite C100H-HCl chromatography system for separating Pt, Au, Ir, Re from non-noble metals. The concentrations of the PGE and 29 trace elements have been measured with combination of the instrumental and radiochemical neutron activation analysis techniques. The concentrations range of the determined elements is from 5.4 to 7.5 × 10⁻⁹ % in mass.
