分析说明

This application demonstrates the suitability of the Ascentis Express HILIC for the analysis of sugars. Structures along with the optimized chromatogram obtained on the Ascentis Express HILIC are presented. Separation is by normal-phase mechanism as a decrease in mobile phase water content results in increased retention.
