Gas chromatography measures leakage into cavity surrounding joint under test. System surrounds joint being tested with sealed cavity. Presence of leakage gas in cavity monitored by gas chromatograph. Leakage rate found by multiplying relative leakage gas concentration by mass flow rate of purge as into cavity.
