Tracer Gas Probes and Whole-Package Accumulation

Use a probe to investigate location

With tracer gas inside a test pack, a sampling probe can survey an accessible seam or closure for a local rise in concentration. Probe distance, speed, airflow and detector response affect the reading. Repeat a local indication with controlled probe movement and check the background before interpreting the location.

Use an enclosure to measure the combined signal

An accumulation test collects tracer gas released from the pack into an enclosure over a defined interval. With a known volume, measured background and validated setup, the change in concentration can support an estimate of total tracer leakage. It combines contributions from the whole pack, so it does not identify the seam or joint responsible.

A whole-pack result can guide a follow-up probe scan. Both measurements depend on tracer concentration, pressure and the test setup. Neither reading directly supplies a liquid-product leak rate.
