Marine tracer gases are specialized gases used to study ocean circulation and biogeochemical processes. Gas systems in marine research involve the precise measurement and distribution of these tracer gases. These systems help track water movement, mixing, and gas exchange in marine environments.

Size: Typically available in cylinders ranging from 1 liter to 50 liters.

Grade: High-purity (99.99% or higher) tracer gases such as SF6, He, or Ar.

Viscosity: Low viscosity, similar to air or lighter gases (e.g., helium).

Buoyancy: Varies by gas; helium is highly buoyant, SF6 is denser than air.

Material: Cylinders made of aluminum or stainless steel; valves and fittings are brass or stainless steel.

Pressure: Stored at high pressures (up to 200 bar or 3000 psi).

Compatibility: Non-reactive with most materials, inert for leak detection.

Detection: Sensitive to gas detectors (e.g., mass spectrometers for SF6).

Temperature Range: Stable across marine environments (-20°C to 50°C).

Regulatory Compliance: Meets ISO, DOT, and IMDG standards for transport and use.
