Leak Detection

Leak Detection for pressure or vacuum integrity can be measured by immersing the part under pressure and bubble checking for gross pressure leaks

Helium Leak Detection of very small leaks is accomplished by pulling a vacuum in bonded enclosures. While under high vacuum, helium gas is injected around the joint. The vacuum pulls any helium leaks into the detector, which is a mass spectrometer tuned to the He gas. Leaks can be measured to the 10-9 Pa·m3·s−1 level
