CN HPLC Columns

CN HPLC Columns Description

CN HPLC columns, which uses Hawach Scientific’s unique innovative filler bonding process, is based on ultra-high purity fully porous spherical silica gel, bonded with cyanopropyl functional groups, and controlled by the strict process to ensure the formation of uniform, dense amino functional molecules. Layers maximize bond coverage, ensure that the column packing has excellent stability.
The reversed-phase cyano HPLC column elutes rapidly for hydrophobic molecules, has unique selectivity for polar compounds, and has good peak shape for separation of strongly basic compounds (including ammonium salts). It has different selectivity from reversed phase columns such as C18 and C8. A cyano column can be used when a highly hydrophobic compound cannot be eluted with a standard C18 and C8 column or a typical reversed-phase eluent.
The normal phase column can replace the silica gel column, which has a fast equilibrium and is more consistent than the activity of the non-derivatized silica gel. It can replace most of the cyano liquid chromatography columns on the market.
