Separating helium and oxygen gases can be achieved using a cryogenic distillation process. This method leverages the difference in boiling points of the gases: helium boils at -268.93°C and oxygen at -182.96°C. By cooling the mixture to a temperature between these points, oxygen will liquefy while helium remains in gaseous form, allowing for easy separation. This technique is widely used in industrial applications for obtaining high-purity gases.
