Chiral Columns, Regis Phase, ES Industries

780201 780101 786615
The Whelk-O 1 is useful for the separation of underivatized enantiomers in a number of families including amides, epoxides, esters, ureas, carbamates, ethers, aziridines, phosphonates, aldehydes, ketones, carboxylic acids, alcohols and non-steroidal anti-inflammatory drugs (NSAIDs).

  • Covalent bonding ensures universal solvent compatibility and excellent durability
  • Fast method development and run times
  • Allows for the inversion of peak elution order
  • Broad versatility comparable to polysaccharide-derived chiral stationary phases
  • Columns are packed and tested at high pressures for use in both SFC and HPLC mode

This π-electron acceptor/π-electron donor phase exhibits an extraordinary degree of generality. The broad versatility observed on the Whelk-O 1 column compares favorably with polysaccharide-derived chiral stationary phases.
