The lithium reagent used in the synthesis of benzene for 14C dating contributes insignificant 14C in high-precision measurements on 7 g benzene samples. Blank experiments on three different batches of lithium yielded small amounts of carbon, most of which probably originated as “memory” in the reaction vessel.
