Description of Spherical CN Flash Columns

The CN Flash Column from Hawach Scientific is packed with a bonded cyano functional group on an ultra purity silica substrate. The polarity is between silicone gel and C18. Spherical CN Flash Columns can be usually used for both normal and reversed phase flash separation.

Compared with traditional reversed-phase C18, C8 chromatography columns, the CN flash chromatography column has weaker hydrophobicity. For some compounds that are strongly retained on C18 and C8 columns, the rapidity separation can be achieved without adjusting the organic phase ratio. CN column has multiple retention mechanisms: the cyano group on its surface will have a strong dipole-dipole interaction with polar compounds, while the propyl chain will provide a hydrophobic effect, giving it unique selectivity and broadening. The scope of chromatographic applications.
