The combination of neutron activation analysis and controlled potential electrolysis has proved itself to be a useful multielement method for the determination of 14 elements in a 500-..mu..L sample of human blood serum. After freeze-drying and irradiation, the samples are decomposed and electrolyzed for 3 h. The radioactive species deposited on the mercury cathode allow simultaneous determination of eight elements (Ag, Au, Cd, Co, Fe, Hg, Sb, Zn). Another six elements (Br, Ca, Cs, Na, Rb, Sc) are determined by measuring the activities in the residual solution. Data illustrating the precision of the method are given. The determination limits are of the order 10/sup -1/-10/sup -3/ ..mu..g/L for the nine trace elements investigated.
