This low-bleed, stable column produces consistent results.

• Polar phase, polyethylene glycol
• Polar-deactivated surface tightly binds polymer for excellent thermal stability
• Resists oxidative damage, damage from strongly acidic or basic volatiles better than silicone solid phases
• Equivalent to USP G14, G15, G20 and G39 phases
• Superior inertness ensures excellent peak shape and sensitivity
