Pure oxygen is a gas that only contains oxygen - and nothing else. Oxygen is pure when a certain mass (or volume) of it contains no other elements.
As I wrote the above, someone else suggested pure oxygen was pure air. Air on earth is mostly nitrogen (about 75%), 20% oxygen, with smaller amounts of argon, water vapor, CO2, and other gasses.
