What is the difference between the Spherisorb OD/CN column, Spherisorb CN/RP, and Spherisorb CN/NP column? - WKB229815

ENVIRONMENT

• column chemistry
• Spherisorb OD/CN
• Spherisorb CN

ANSWER

The Spherisorb OD/CN is a silica particle surface bonded with C18 and Cyano (nitrile) ligands. The Spherisorb RP/CN is shipped/ stored in a reverse phase solvent and NP/CN is shipped/ stored in a normal phase solvent silica particle surface bonded with Cyano (nitrile) ligand.

ADDITIONAL INFORMATION

The Spherisorb OD/CN and Spherisorb CN are different column chemistries and there is potential for chromatographic retention and selectivity differences.
