Restek Viva C8 Columns USP L7

particle size: 5μm, spherical
pore size: 300Å
carbon load: 5%
endcap: yes
pH range: 2.5 to 8
temperature limit: 80°C
Highly base-deactivated wide pore packing that exhibits excellent peak shape for a wide range of compounds. Less retention in reversed phase assays than Viva C18. Similar Phase(s):

BioBasic 8, Zorbax 300 OSB C8, Synchropak C8, 208 TP C8

particle size: 3μm or 5μm, spherical
pore size: 110Å
carbon load: 7%
endcap: fully endcapped
pH range: 2.5 to 8
temperature limit: 80°C
Reliable performance and symmetric peaks for neutral to acidic compounds. Provides shorter retention times for hydrophobic compounds, compared to C18 phases. Replaces Hypersil^® C8 and Pinnacle^® C8. Similar Phase(s):

Hypersil C8

particle size: 1.9μm, 3μm, or 5μm, spherical
pore size: 140Å
carbon load: 6%
endcap: yes
pH range: 2.5 to 8
temperature limit: 80°C
Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle^® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for reducing analysis time, if resolution is adequate. Replaces Hypersil^® BDS C8 and Pinnacle^® C8 Amine. Similar Phase(s):

Hypersil BDS C8, Spherisorb C8

Excellent for a wide range of analyses

particle size: 3μm or 5μm, spherical
pore size: 100Å
carbon load: 12%
endcap: fully endcapped
pH range: 2.5 to 8
temperature limit: 80°C
A retentive, high-purity, base-deactivated reversed phase packing that exhibits excellent peak shape for a wide range of compounds. Less retention for neutral, hydrophobic compounds, compared to the Ultra C18 column. Similar Phase(s):

Luna C8, Symmetry C8, Hypersil Gold C8
