Abstract The feasibility of utilizing liquid scintillation counting as a detection method for the liquid chromatographic analysis of99Tc is evaluated. The chemical quenching of constituents commonly found in liquid chromatographic mobile phases is investigated, and quench corrections are presented. Quantification of99Tc is achieved over a concentration range of 10−3 to 10−8M on quiescent KTCO4 solutions, with sample volumes of 0.3 ml, yielding a counting efficiency from 51 to 59% for a narrow 150 channel window. The potential for the double isotope labelling of technetium complexes and the implications of the liquid scintillation counting of99Tc in flowing eluents are discussed.
