You can't get 100% pure oxygen in everyday life, but you can find it in specific contexts like:
- Medical Oxygen: Hospitals and healthcare facilities use oxygen concentrators to produce high-concentration oxygen for patients who need supplemental oxygen. These machines filter out nitrogen from the air, leaving behind a concentrated stream of oxygen.
- Industrial Applications: Industries like welding and metal fabrication use oxygen cylinders containing 99.5% pure oxygen, which is used for combustion and cutting processes.
- Scientific Research: Laboratories often require high-purity oxygen for experiments and research. This is typically achieved through fractional distillation of liquid air, which separates oxygen from nitrogen.
It's important to note that breathing 100% pure oxygen for extended periods can be harmful and potentially dangerous. Always consult a medical professional for any oxygen therapy needs.
