A simple method to identify and determine Selenomethionine (SeMet) and Selenomethylselenocysteine (Se-MeSeCys) with diethyl ethoxymethylenemalonate (DEEMM) derivatization and LC-ESI-MS/MS determination was developed. Separation of SeMet and Se-MeSeCys was achieved in 15.3 minutes. The calibration graph was linear in the range
