Column: CN-3 250 x 4.6mm ; Order No. : 1060L250W046
Normal Phase Eluent: Hexane/EtOH 90/10 Flow: 1.0 ml/min Temp: 40°C Detection: UV @ 220nm  Sample: As indicated
Reverse Phase Eluent: MeCN/Water 35:65 Flow: 1.0 ml/min Temp: 25°C Detection: UV @ 220nm  Sample: As indicated

Notes: 
The versatility of Inertsil CN-3 makes is a useful alternative when ODS or C8 phases don't work. 
 

GL Sciences' unique, super high density bonding procedure has produced a CN phase that eliminates the instability and irreproducibility that plagued standard CN phases.  CN-3 offers unique selectivity, long column operating life, and excellent peak shapes in both reverse phase and normal phase modes.

The Inertsil 3-series represents a major advance in performance over the original Inertsil 2-Series. Inertsil 3-Series phases, including ODS-3, ODS-SPRINT, ODS-3V, ODS-P, ODS-EP, C8-3, Ph-3, CN-3, NH2, Diol, and SIL-100Å, are based on a purer, higher surface area silica which is specially manufactured to provide maximum bonded phase coverage.  The result is a series of columns which provide excellent peak shapes using simple eluents while operating at low pressure.

 Inertsil CN-3 is available in 5 micron particle sizes in column configurations ranging from capillary to 50mm ID preparative sizes.

GL Sciences has compiled a vast collection of chromatographic applications data on CN-3 and their other phases which can assist you in method development.  These can be accessed under the "chromatograms" link on the main menu bar above, by searching for a particular compound using our "search" link above, or by clicking here.
 
By choosing Inertsil CN-3, you can be assured  that you are using one of the most trusted, popular, and enduring HPLC columns in the history of HPLC.

* Inertsil phases are known to provide excellent results and long column life at pH levels of 9 or 10. 
However, optimum column life will likely be achieved by operating at a pH of between 2 and 7.5.
