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.

(USP L10)
Chromatographic Properties
The general-purpose Restek® Amino is an aminopropylsilane that offers reproducible retention
and efficiency. It is a great choice for the normal-phase or HILIC analysis of simple sugars.
Ultra Amino Columns
(USP L8)
Chromatographic Properties
Base-deactivated spherical silica is useful for normal-phase or HILIC separations.
