Stable from 100% Organic to 100% Aqueous
Prevail™ HPLC columns offer exceptional versatility for difficult separations. Traditional reversed-phase packings experience bonded phase collapse under highly aqueous (>95%) conditions. Prevail™ bonded phases remain fully extended in 100% aqueous and offer a high carbon load for exceptional retention at 100% organic. Retain both polar and nonpolar compounds simply by adjusting the mobile phase.
Highly polar phase. General purpose normal phase applications.
