Description

Analysis Note This application shows the analysis of sugars by HILIC Chromatography with ELSD detection. The purpose of the work shown here was to develop a HILIC method that could quickly separate mono- and di-saccharides with good sensitivity and reproducibility utilizing the Ascentis Express OH-5 column and an Evaporative Light Scattering Detecctor (ELSD) detector.
