Ultra Aromax is a unique reversed-phase material that exhibits extreme retention and selectivity for aromatic and/or unsaturated compounds. This column is a great alternative to our Biphenyl phase when increased retention is required, and it’s an excellent choice for gradient LC-MS analyses when conventional columns are not giving adequate retention or selectivity.

particle size: 5µm, spherical
pore size: 60Å
carbon load: 27%
endcap: fully endcapped
pH range: 2.5 to 8
temperature limit: 80°C

Most retentive of our alkyl stationary phases due to large surface area of the base silica and high-density bondings. Provides excellent peak shapes for a wide range of compounds.

particle size: 3 µm or 5 µm, spherical
pore size: 100 Å
carbon load: 12%
end-cap: yes
pH range: 2.5 to 8
temperature limit: 80 °C
USP phase code: L7
phase category: C8, octylsilane
ligand type: monomeric C8

Our C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. Like our C18, this general-purpose Restek C8 is suitable for a wide range of compounds from acidic through slightly basic.

end-cap: yes
pH range: 2.5 to 8
temperature limit: 80 °C
USP phase code: L1
phase category: C18, octadecylsilane
