Analysis of Erythrose and Threose (SC1011)

Print

Threose and its isomer, erythrose, are rare sugars which only exist in nature in small amounts. They are tetroses that contain four carbons in their structures. In this application, a ligand exchange column, SUGAR SC1011 was used to analyze threose and erythrose. The SC1011 is suitable for the separations of isomers such as threose and erythrose.
