Two GC-MS methods for the enantioselective separation of the 20 proteinogenic amino acids are compared. Ethyl chloroformate and 2-chloropropanol were used to derivatize amino acid enantiomers. The diastereomers formed were separated on a non-chiral column by capillary gas chromatography. The separation performances were compared to those obtained when using non-chiral derivatization on a chiral column. (c) 2007 Elsevier B.V. All rights reserved.
