The tracer gas method using hydrogen is one of the most sensitive and accurate leak detection techniques in industry. It allows localization of even the smallest leaks in pressure, vacuum, and technological installations. How does this method work and why is it so effective?

Principle of the hydrogen method

The hydrogen method involves introducing a gas mixture containing hydrogen (usually 5% H₂ in nitrogen N₂) as a tracer gas into the tested installation. Due to the very small size of hydrogen molecules, this gas penetrates even the smallest leaks that could remain undetected using other methods.

Advantages of the hydrogen method

  • Highest sensitivity Ability to detect leaks in the order of 10⁻⁶ mbar·l/s, making this method one of the most sensitive available techniques.
  • Safety of use Use of 5% H₂ in N₂ mixture eliminates ignition risk, as hydrogen concentration is below the lower explosive limit.
  • Universal application The method is suitable for testing both pressure and vacuum installations, regardless of their complexity.
  • Testing speed Immediate detector response allows efficient testing of even extensive installations.
  • Precise localization Ability to indicate exact leak location facilitates repair planning.

Applications of the hydrogen method

The hydrogen method finds wide application in various industrial sectors:

  • Petrochemical industry - testing of tanks, pipelines, heat exchangers
  • Chemical industry - leak control of reactors, distillation columns
  • Energy sector - testing of boilers, turbine units, cooling systems
  • Food industry - control of vacuum installations, CIP systems
  • Pharmaceuticals - verification of sterile installation tightness
