The Restek aqueous C18 is a rugged, reversed-phase column with a well-balanced retention profile.

• Particle Size: 1.9, 3, or 5 µm, spherical
• Pore size: 140 Å
• Carbon load: 6%
• Temperature Limit and pH range: 80 °C and 2.5 to 8
• USP phase code: L1
• Phase category: modified C18
• Ligand type: proprietary polar modified and functionally bonded C18

They can effectively retain more types of solutes than a conventional C18 and is ideal for multicomponent LC-MS analyses. The general-purpose Aqueous C18 boasts high reproducibility and compatibility with many mobile phase conditions—even 100% aqueous. And when used with a gradient, these columns eliminate the all-too-common issue of multiple compounds eluting near the column void time.
