Comparison of test results with leak detector and ...

Leak detectors for the tracer gas helium are not currently designed on the basis of quadrupole mass spectrometers. Their greater robustness and long-term stability as well as the easier quantification of results and data interpretation have resulted in the fact that above all mass spectrometric detectors on the basis of magnetic sector mass spectrometer are mainly used for this purpose.

Helium Leak Testing Companies | Applied Technical Services

The Helium Leak rate can be reported as a quantitative (amount of leak rate) measurement. Helium leak testing can also be used to identify the location of very small leaks. Helium Leak testing may be used by customers to assess the performance of a component or a system, or to analyze or evaluate product longevity.

A helium leak test cycle can be broken down in two primary phases, the pump down step and the helium measurement step. The pump down time is the time required to achieve a specific vacuum level inside the part or inside the test chamber where a pressurized part is placed (depending on the approach—"in-leakage" vs "out-leakage").

Helium Leak Testing | Leak testing | LACO Technologies

Helium Leak Testing, Leak Testing, helium, As explained in Helium Consumption Reduction there are a couple of key factors that make helium an ideal tracer gas for leak testing, namely its low concentration in the environment and its small atomic mass. However, due to helium shortages and consequent expense, we have also discussed ways of reducing helium consumption.
