Methods:
Vacuum Method
In the vacuum method test gas is blown against the wall of the evacuated sample from the atmosphere side. It enters the sample at leaks and is fed to the leak detector.
The sample must be vacuum pressure-proof.
The sensitivity stages GROSS ---FINE---ULTRA are run through.
The detection limit is lower than in the sniffing method. The helium concentration at the leak must be known in order to quantify the leak. The state of equilibrium must be waited for.
Sniffing Method
In the sniffing method the test gas escaping from leaks in the sample into the atmosphere is detected.
The sample must withstand the applied test pressure.
In operation with the sniffing probe a constant gas flow is sucked in from the atmosphere. The helium proportion of the air (5.2 ppm) causes a leak rate display of approx. 1*10-6 mbar l/s which can be eliminated by the ZERO function.20 3 Description Operating Instructions, ikna88en1-01, 1605
To detect a leak, the sniffing probe is applied to the points of the sample under helium overpressure which are suspected of leaking. An increased leak rate value indicates an increased concentration of helium and therefore a leak. The higher the pressure and the helium concentration in the sample, the smaller the leaks which can be detected.
The sensitivity stages GROSS---FINE are run through.
The detection sensitivity and the quantifiability of the leak rate are less favourable than in the vacuum pressure leak detection.
