Ultra C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase.

• Particle size and pore size: 3 or 5 µm, spherical and 100 Å
• Carbon load: 12%
• End-aap: yes
• pH range and temperature limit: 2.5 to 8 and 80 °C
• USP phase code: L7
• Phase category: C8, octylsilane
• Ligand type: monomeric C8

Like Restek's C18, this general-purpose Restek C8 is suitable for a wide range of compounds from acidic through slightly basic.
