For labelling organic or anorganic substances with technetium-99m in the heterogenous phase, an aqueous solution of the substance to be labelled is mixed with a pertechnetate and an aqueous suspension of Sn2Fe(CN)6, Sn3[Fe(CN)6]2, SnS or SnTe and the solution of the labelled substance is separated from the solid phase after completion of the reduction of the pertechnetate. In particular, the reducing agent can be in a vial, in lyophilized or adsorbed form, as appropriate together with the substance to be labeled. |
