General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

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).
