The determination of tin in biological material by using neutron-activation analysis

Abstract

A method for the determination of tin in biological material, by using neutron-activation analysis and radiochemical separation of tin-121, is described. Decontamination from sodium and antimony was shown to be satisfactory by tracer techniques, and the method was applied to biological standard materials and other samples. The precision is ±10 per cent. at the submicrogram level, and the sensitivity (which could be lowered by increasing the neutron flux) was found to be 10 to 20 ng.
