Chromatographic Properties
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.

Chromatographic Properties
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.
