Introduction
| Category | Details |
|---|---|
| Composition | – Nitrogen (N₂): Balance gas (typically 70–95% by volume) |
| – Nitric Oxide (NO): 1–1000 ppm (toxic, regulates atmospheric chemistry) | |
| – Propane (C₃H₈): 50–10.000 ppm (flammable hydrocarbon) | |
| – Carbon Monoxide (CO): 1–5000 ppm (toxic, asphyxiant) | |
| – Carbon Dioxide (CO₂): 0.1–10% (inert, greenhouse gas) | |
| Key Applications | – Environmental Science: Air quality monitoring (NOx, CO, CO₂ emissions) |
| – Industrial Safety: Calibrating gas detectors for confined spaces | |
| – Automotive: Testing exhaust emissions systems | |
| – Medical Research: Respiratory physiology studies | |
| Physical Properties | – Colorless, odorless mixture (CO has faint sweet odor at high concentrations) |
| – Flammable (due to C₃H₈); explosive range: 2.1–9.5% propane in air | |
| – Toxic components (NO, CO) require stringent handling | |
| Safety Precautions | – Toxicity: Use in ventilated areas; avoid inhalation (NO/CO poisonings) |
| – Fire Risk: Eliminate ignition sources (propane is flammable) | |
| – Pressure Handling: Store cylinders upright; secure against falls | |
| Storage & Handling | – High-pressure cylinders (e.g., 10L, 50L) with CGA/DIN valves |
| – Store below 50°C, away from direct sunlight and incompatible gases (e.g., oxidizers) | |
| – Shelf life: 12–24 months (certified stability) | |
| Certifications | Compliance with ISO 17025 (calibration), OSHA/EPA regulations, and ASTM D1945 (natural gas analysis) |
| Environmental Note | – CO and NO are precursors to smog and acid rain |
| – CO₂ contributes to climate change; handle with carbon capture awareness |
