General description
Application
- Enantioselective separation of amino acids as biomarkers indicating life in extraterrestrial environments.: Research on using pyridine-based chromatography for the enantioselective separation of amino acids, which can help in the search for extraterrestrial life by analyzing amino acid chirality (Pietrogrande, 2013).
