- Title
Direct Analysis of Amino Acids by HILIC-ESI-MS.
- Authors
Schriewer, Alexander; Theilen, Katharina Johanna; Hayen, Heiko; Wen Jiang
- Abstract
The article discusses the use of hydrophilic interaction liquid chromatography coupled to electrospray ionization mass spectrometry (HILIC-ESI-MS) to simultaneously determine 14 standards of proteinogenic amino acids. Topics covered include retention times, isoelectric point, and classification of amino acids. Also mentioned are amino acids with a nonpolar side chain like tryptophan, phenylalanine and leucine, and polar amino acids like proline, glutamine, or asparagine.
