Efficiency of Separation for Uracil and Uridine in HILIC Mode

Uracil and Uridine are nucleosides which occur as a part of RNA. Both compounds are neutral in nature and very polar. Uracil is often used as a void marker in reversed-phase HPLC. A fast HILIC-based method was developed for analysis of uracil and uridine on the core-shell HILIC and cation-exchange column. Method provides good peak shape and retention control. Column and method can be used for analysis of polar compounds in HILIC, and HILIC/mixed-mode.
