Thirteen geochemical reference standards have been analysed for lithium by a technique originally developed for assay of lithium in biological materials. The technique consists of thermal neutron irradiation, then measurement of 3 He from decay of 3 H produced via the reaction 6 Li(n, α) 3 H. The results are compared with literature values.
