Helium mass spectrometer leak detectors are used in production line industries such as refrigeration and air conditioning, automotive parts, carbonated beverage containers food packages and aerosol packaging, as well as in the manufacture of steam products, gas bottles, fire extinguishers, tire valves, and numerous other products including all ...
Several tracer-gas leak testing methods exist, including: Detection of leaks using helium mass spectrometer, which provides high sensitivity; Hydrogen leak testing, which provides the best mobility; Refrigerant gas leak detection, for refrigeration applications
ASTM E493- Standard Test Methods for Leaks Using the Mass Spectrometer Leak Detector in the Inside-Out Testing Mode ASTM F2338- Standard Test Method for Nondestructive Detection of Leaks in Packages by Vacuum Decay Method ASTM F2391- Standard Test Method for Measuring Package and Seal Integrity Using Helium as the Tracer Gas
Leak testing (LT) or Leak detection. Hydrostatic test; Absolute pressure leak testing (pressure change) Bubble testing; Halogen diode leak testing; Hydrogen leak testing; Mass spectrometer leak testing; Tracer-gas leak testing method for helium, hydrogen and refrigerant gases; Machine vision based automatic inspection
A variety of methods for leak detection exist. Large leaks can be found by pressurizing the chamber, and looking for bubbles in soapy water, while tiny leaks can require more sensitive methods, up to using a tracer gas and specialized Helium mass spectrometer.
The helium leak was a setback for SpaceX, which has been ferrying NASA astronauts to and from the International Space Station since 2020. SpaceX carried its first private citizens into orbit in ...
