Yes. Air can be separated through fractional distillation. The air must be cooled to a liquid first. Considering nitrogen oxygen and argon all have different boiling points, the liquid air mixture can be heated very gently and carefully in a fractionating column. Each element will eventually vaporise and they can be condensed and collected at different points up the fractionating column because they each have different boiling points.
