Helium is commonly used as a tracer gas for leakage measurements across the world. This gas is easy to use without safety issues and enables to measure a very wide magnitude of leakage rates with well proven detectors (Mass Spectrometers). Nevertheless, shortage and price increase of helium in several world areas, encourage industry users to look for alternative tracing gases for leakage measurement.
