Restek Ultra AQ C18 5um, 250 x 10mm Confirm customer has evaluated an analytical size column

Overview

Features & Benefits

Our broadest selection of stationary phases, including unique phases. High-density bondings for maximum retention. High-purity, Type-B silica gives excellent peak shapes for a wide range of compounds.

Note: We strongly recommend ordering a semi-prep or prep column only after evaluating the desired separation on an equivalent analytical-scale column. Because we cannot reuse a column or the silica it contains once it has left our facility, we cannot accept returns of large-scale columns.

Description

• Easy scale-up from Restek analytical columns.
• Popular bonded phases.

Restek makes it easy to scale up your separations. We offer a wide range of semipreparative and preparative-scale columns packed with many of our popular Ultra, Allure, Pinnacle DB, and Viva bonded phases on a 5 μm spherical silica. Other stationary phases are also available—please call and inquire.

The Restek Aqueous C18 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 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, it eliminates the all-too-common issue of multiple compounds eluting near the column void time.
