Dealing With the Helium Shortage | ASSEMBLY

"The biggest benefit of using helium is that it's a nonreactive gas, so it doesn't get outgassed by any other process," explains Splete. "That makes it easier to control than other types of gases." Aside from the price of the gas itself, helium leak testing is typically more expensive than other types of methods, such as pressure decay.

from air to vacuum. The small diameter of the helium atoms allows the detection of very small leaks. As the speed of helium is three times higher than the speed of air, the amount of helium entering through a leak and thus the sensitivity is increased by a factor of 3 compared to air. Alternatively, argon is frequently used as tracer gas.
