Ultra HPLC Prep Columns

Restek's 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.

Ultra Aqueous C18 HPLC Prep Columns

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.

  • Stationary Phase Category: modified C18 (L1)
  • Ligand Type: proprietary polar modified and functionally bonded C18
  • Particle: 5µm, spherical
  • Pore Size: 100 Å
  • Carbon Load: 15%
  • End-Cap: no

Ultra IBD HPLC Prep Columns

The Restek IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today. With a unique polar group, this column is very retentive and selective for acids. It also provides symmetrical peak shape for strong bases. Restek’s IBD is compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.

  • Stationary Phase Category: polar-embedded alkyl (L68)
  • Ligand Type: proprietary polar functional embedded alkyl
  • Particle: 5µm, spherical

Ultra PFP Propyl HPLC Prep Columns

The Restek PFP Propyl is a great choice for the retention and selectivity of charged bases, electronegative compounds, and amine-containing compounds. Unlike a conventional cyano column, the Restek PFP Propyl is much more amenable to LC-MS because it is more reliable and efficient with acidic mobile phases. This versatile column is also compatible with highly aqueous mobile phases and HILIC separations.

  • Stationary Phase Category: fluorophenyl propyl (L43)
  • Ligand Type: pentafluorophenyl propyl
  • Particle: 5µm, spherical
  • Pore Size: 100 Å

Ultra Cyano HPLC Prep Columns

The Restek Cyano is a traditional monomeric cyanopropylsilane that is recommended for assays where alternate selectivity, or confirmation, to a C18 or C8 column is desired. It can be used in normal-phase, reversed-phase (best with mobile phase pH between 5 and 7), and HILIC modes. It is an excellent choice for the analysis of protonated bases.

  • Stationary Phase Category: cyano (L10)
  • Ligand Type: cyanopropylsilane
  • Particle: 5µm, spherical
  • Pore Size: 100 Å
  • Carbon Load: 8%
  • End-Cap: yes
  • Surface Area: 300 m2/g
  • pH Range: 2.5 to 8
  • Maximum Temperature: 80°C
