Ultra Aqueous C18 Columns (USP L1), Particle Size 3 μm, Length 50 mm, ID 3.0 mm, Restek (CAT#: STEM-C-0996-LC)

The Ultra Aqueous C18 Columns (USP L1) manufactured by Restek are made of high-purity, type-B silica that minimizes activity and creates high-density bonding. These columns are ideal for selective and reliable HPLC applications.
The Ultra Aqueous C18 Columns (USP L1) is a rugged, reversed-phase column with a well-balanced retention profile. It can effectively retain more types of solutes than a conventional C18 and is an ideal choice for multicomponent LC-MS analyses. The Ultra Aqueous C18 Column boasts high reproducibility and compatibility with many mobile phase conditions-even 100% aqueous. And when used with a gradient, it eliminates the all-too-common issue of multiple compounds eluting near the column void time.
