Agilent Urea Analysis Application Note

This document introduces a method for analyzing highly hydrophilic compounds using the Agilent ZORBAX Rx-SIL column and a reversed-phase mobile phase. This method can effectively separate urea and uracil, which are both unretained by reversed-phase columns because they are highly hydrophilic.

About this manual

Organic Chemicals Robert Ricker explains that amines, urea, and uracil can be difficult to analyze by standard reversed-phase HPLC due to excessive retention or lack of retention. The document presents a solution using the Agilent ZORBAX Rx-SIL column with a specific mobile phase to achieve rugged chromatography for these hydrophilic compounds.
