The unique cyano chemistry of YMC-Pack Cyano provides a different selectivity from both phenyl and standard aliphatic (C18, C8 or C4) reversed phase packings.
Cyano packings also provide an alternative to silica material in normal phase chromatography, where bonded normal phase packings have the advantage of faster equilibration, more uniform surface activity and increased resistance to dissolution.
To extend column lifetime continued switching between normal and reversed phase solvents should be avoided.

Column care
YMC-Pack Cyano is stable towards hydrolysis between pH 2-7,5 . Remove acid and buffer salts before storage. For detailed information please refer to the “Column Care and Use Instructions” which are shipped with each analytical column.
