LACO is uniquely qualified as one of the few suppliers in the market with experience designing Non-Helium Tracer Gas Leak Test Systems. Using a variety of instruments and methods, we have developed production leak testing systems detecting non-helium tracer gases such as:

  • All types of refrigerants, including R410a, R134a, and others
  • Argon
  • Carbon Dioxide
  • Nitrogen
  • Krypton
  • Hydrogen
  • Methane
  • Ammonia
  • Sulfur Hexafluoride (SF6)

Gas sensor technologies we use to detect these other tracer gases include:

  • Magnetic sector mass spectrometers (for hydrogen)
  • Residual Gas Analyzers (RGA's)
  • Thermal Conductivity Sensors
  • Chemical Sensors (for hydrogen)
  • Infrared Sensors

These systems are used in the Refrigeration & Air Conditioning, Automotive, Power Transmission, Medical/Pharmaceutical, Aerospace, and Defense industries.

Helium is normally the most common tracer gas for production leak testing, with flexible test methods and best ultimate sensitivity. However, when helium is too costly, or if another gas is already used in the product, an alternate tracer gas may be used. This is most common when the product is already prefilled with the gas.
