锗烷 Detection
Formula GeH₄ · CAS 7782-65-2 · 烷烃（可燃）
Hazards & Toxic Symptoms
Germane is an alkane combustible gas or liquid (saturated hydrocarbon chain), which is colorless and flammable. When mixed with air, it forms an explosive mixture. It has low toxicity, and the main risks are: ① fire explosion (lower explosion limit is usually 1-10%); ② high concentration in enclosed spaces displaces oxygen, leading to simple asphyxia; ③ long-term exposure to high concentrations may cause mild anesthesia and dizziness. Alkanes heavier than air tend to accumulate on the ground/in low-lying areas. Storage sites must be equipped with LEL monitoring and mandatory ventilation.
Typical Application Scenarios
- Combustible gas leakage monitoring in chemical plant areas
- Gas station / LPG / Liquefied gas storage tank area
- Gas pipeline network inspection
- Laboratory fume hood LEL monitoring
Detection Principle / Recommended Sensors
Catalytic combustion (LEL universal) / Infrared (high concentration/hypoxia scenarios) / PID (vapor VOC)
Common Range：0-100% LEL
