Introduction
| Category | Details |
|---|---|
| Composition | – Nitrogen (N₂): Balance gas (typically 60–90% by volume) |
| – Carbon Monoxide (CO): 1–5000 ppm (toxic, combustion byproduct) | |
| – Helium (He): 1–20% (inert carrier, cryogenic cooling) | |
| – Oxygen (O₂): 1–10% (oxidizing agent, medical use) | |
| Key Applications | – Environmental Science: Air quality monitoring (CO emissions) |
| – Medical Research: Respiratory physiology and hyperbaric chambers | |
| – Industrial Safety: Calibrating multi-gas detectors (CO/O₂/flammables) | |
| – Welding: Shielding gas mixtures (e.g., He/O₂ for titanium) | |
| Physical Properties | – Toxicity: CO is odorless, tasteless, and lethal at high concentrations |
| – Flammability: O₂-enriched atmospheres increase fire risks | |
| – Helium: Lightest gas (0.1785 g/L), non-flammable | |
| Safety Precautions | – CO Exposure: Use in ventilated areas; monitor with real-time detectors (≤25 ppm TWA) |
| – Oxygen Enrichment: Avoid oils/greases (risk of spontaneous combustion) | |
| – Asphyxiation: Ensure O₂ levels ≥19.5% in confined spaces | |
| Storage & Handling | – High-pressure cylinders (e.g., 50L, 100L) at 150–200 bar pressure |
| – Store away from flammables/oxidizers; secure cylinders upright | |
| – Liquid helium requires cryogenic dewars and PPE (gloves, goggles) | |
| Certifications | Compliance with ISO 17025 (calibration), OSHA/EPA regulations, and ASTM D7606 (cryogenic safety) |
| Environmental Impact | – CO contributes to smog and ground-level ozone |
| – Helium is a non-renewable resource; prioritize recycling | |
| Shelf Life | 12–24 months when stored under recommended conditions (temperature: 15–25°C) |
