Hello Salma

You can use a chiral capillary column such as Lipodex or Hydrodex  with cyclodextrin stationary phase .Lipodex are lipophilic phases where as Hydrodex are hydrophilic in nature. I don't know the nature of your compounds but you can give a trial. 

Alternatively HPLC with chiral column is better choice for separation of enantiomers .
