Helium mass spectrometer - Wikipedia CachedA helium mass spectrometer is an instrument commonly used to detect and locate small leaks. It was initially developed in the Manhattan Project during World War II to find extremely small leaks in the gas diffusion process of uranium enrichment plants. It typically uses a vacuum chamber in which a sealed container filled with helium is placed. Helium leaks out of the container, and the rate of the leak is detected by a mass spectrometer.

Vacuum Leak Detectors and Helium Leak Detectors CachedHelium leak detection is extremely accurate, quantitative and repeatable. Fast cycle times are a further advantage. Manual sniffing or spraying is often the easiest way to detect a leak with Helium. But it is also possible to use automatic leak detection solutions which are independent of the operator and provide a considerably higher detecting speed.
