C8
Chromatographic Properties
Our C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to pro-
vide 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.
Ultra C8 Columns (USP L7)
Chromatographic Properties
Exceptionally stable C4 packing with high bonding coverage and base deactivation.
Less retention than C18 or C8 phases.
