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.

• Particle size and pore Size: 3 or 5 µm, spherical and 100 Å
• Carbon load: 8%
• End-cap: yes
• pH range and temperature limit:2.5 to 8 and 80 °C
• USP phase code: L10
• Phase category: cyano
• Ligand type: cyanopropylsilane

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.
