Description
To be labeled Oxygen, USP, the gas cylinder must contain a documented minimum of 99.0 percent oxygen by volume and be odor free. The label must also specify whether the oxygen gas was produced by the fractional distillation of air (also called air-liquefaction process) or other means. If produced from liquid air, then the cylinder contents may be labeled USP without an analysis for either carbon dioxide (CO2) or carbon monoxide (CO).
