Helium leak testing is a non-destructive method used to detect and quantify leaks in sealed components or systems. This technique relies on helium's properties as a small, inert, and easily detectable gas. The process typically involves introducing helium into the part or system under test, either by flooding the exterior or by filling it internally. A mass spectrometer, specifically tuned to detect helium, is then used to scan the exterior of the component. If a leak is present, helium atoms will escape from the pressurized area and be detected by the spectrometer, indicating the presence and location of the leak.

The sensitivity of helium leak detection makes it suitable for identifying even very small leaks, often in the range of 10^-6 to 10^-12 mbar*L/s. This high sensitivity is crucial in applications where even minute leaks can compromise performance or safety. Industries that commonly employ helium leak testing include aerospace, automotive, medical device manufacturing, vacuum technology, and semiconductor production. Examples of components tested include vacuum chambers, fuel tanks, medical implants, and integrated circuits. The test can be performed in various configurations, such as direct or vacuum leak testing, depending on the nature of the component and the desired level of precision. Helium leak testing is valued for its accuracy, reliability, and ability to provide quantitative leak rate data.
