Abstract
A method for monitoring a gas leakage rate from a hermetically sealed device, such as a hermetically sealed data storage device with an interior helium atmosphere. In some embodiments, a diffusion rate of inert gas from a hermetically sealed first device is monitored until steady state diffusion is reached, and a standard time constant for the first device is identified. Next, the diffusion rate is monitored for a second sealed device for a portion of the time required for the first device to achieve steady state diffusion, and the time required for the second device to reach steady state diffusion using the standard time constant is calculated.
