An eluate is the solvent containing the decay product when a generator is eluted (gathering the daughter radionuclide from a generator using a suitable solvent).

See also Generator.

A generator is used in nuclear medicine to provide a radioisotope used for a scintigraphic procedure. A generator contains a radionuclide (e.g. molybdenum) that decays to another radionuclide (decay product, e.g. technetium) that can be extracted and used. The original radionuclide is firmly bound in the generator and remains behind.
