How do you detect a helium leak?
This can be conducted in one of 3 ways:
Detector-probe technique, Tracer-probe technique, or Hood technique
. The detector-probe helium leak test is conducted by pressurising a component with helium gas, and then scanning the component by “sniffing” for the presence of helium with the detector probe.

What are the pros and cons of helium leak test?
Helium is undoubtedly more sensitive than air for detecting very small leaks
(less than 1 x 10-3 cc/sec). However, such tiny pinholes of just a few microns do not appear to be a problem in practice, possibly because dissolved solids in the can's contents block the defect.

What is the leak rate for helium detector?
A leak rate of
1.0·10
-
12
mbar·l/s
corresponds to hole diameter of 1 angstrom (Å); this is the lower detection limit for modern helium leak detectors.

How does a helium leak detector work?
Helium leak detectors operate
based on the principle of mass spectrometry
. When a system is suspected of having a leak, it is evacuated and then filled with helium. Being one of the smallest and lightest molecules, helium has an innate ability to pass through even the tiniest of openings.
