General description

Discovery® HS PEG bonded phase provides reversed-phase separations that are distinctly different from C18 columns. It is an ideal candidate to choose when C18 columns give too much retention, when there is too much wasted space between peaks, or when you want to convert a gradient to an isocratic separation.
