Chiral Column

Chiral column is an important part of chiral isolation which is the most environment-friendly method to separate chiral chemicals in the world.  Using Supercritical Fluid Chromatography (SFC) with CO2, there are no toxic separate media involved or discharged during the production. GALAK chiral column have many advantages.

  • Reduce medicine production cost, No emissions of toxic substances
  • High purification of the target substance
  • Widely applied for different chiral chemicals
  • Long life-time, Renewable

chiral seperation


  1. Strictly operate according to the chiral technical manual.
  2. Do not use the following chemicals as flowing phases or solvents, they cost irreversible destruction for chiral media: DMF, DMSO, Dioxane, Toluene, THF, Chloroform, Dichloromethane, Acetone, Ethyl acetate.
  3. Contact us immediately, when there is any question during operation.
