How to purge etanol with nitrogen or other inert gas?

Hi to all,I dissolved calcitriol with ethanol and since calcitriol is cholesterol derivative it is important the remove any dissolved oxygen in the ethanol to maintain stability. I watched several videos and done several attempts with ethanol to optimize the time, pressure, etc...But unfortunately, ethanol evaporated on every attemp. Someone suggested to apply 5030C PURGE-AND-TRAP method but I d'ont think I have the equipment. Any suggestions? Thanks.
