| Abstract: | Summary Stationary phases containing bonded nitrile groups have been synthesized. The effect of the n-alkyl chain length connecting
the nitrile groups to the surface and of the end-capping on the chromatographic properties was studied. The synthesized material
was compared with commercial nitrile phases in the separation of isomeric cresols and xylenols. |
