Commercial helium permeation leak standards: Their ...

The most commonly used leak is the helium permeation type, which uses a glass, quartz, or polymer barrier to restrict the flow of helium via diffusion. Physical leaks, on the other hand, use a physically restrictive element to limit the flow. This article will discuss the properties and reliability of helium permeation standard leaks, based on

Ultimate Guide to Vacuum Leak Detection

It must be noted that the only credible method to detect leaks smaller than 1x10-6 mbar*l/s is with a helium leak detector. A leak diameter for 1x10-12 mbar*l/s (which equates to 1Å) is also the diameter of a helium molecule, which is the smallest detectable leak rate. (N.B. A leak rate of 1 mbar*l/s means a rise of 1 mbar from a 1 litre vessel in a second.
