Selenomethionine Enriched with
76
Se
A quantity of
76
Se-enriched selenomethionine was prepared from
76
Se-enriched
selenium obtained from a commercial supplier.
The primary use of this material is as a spike material for the determination of
selenomethionine by species-specific isotope dilution with HPLC-ICP-MS, in
combination with a standard of selenomethionine with natural isotopic composition.
