2. Helium mass spectrometer - Wikipedia

   en.wikipedia.org/wiki/Helium_mass_spectrometer

   Helium is used as a tracer because it penetrates small leaks rapidly. Helium also has the properties of being non-toxic, chemically inert and present in the atmosphere only in minute quantities (5 ppm). Typically a helium leak detector will be used to measure leaks in the range of 10 −5 to 10 −12 Pa·m 3 ·s −1.

3. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.

4. Tracer-gas leak testing - Wikipedia

   en.wikipedia.org/wiki/Tracer-gas_leak_testing

   A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.

5. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...

   Based on type, the helium market is segmented into liquid and gas. The gas segment held a larger share of the market in 2023. In terms of application, the helium market is categorized into breathing mixes, cryogenics, leak detection, pressurizing and purging, welding, controlled atmosphere, semiconductor, MRI, and others.

7. Pulsed discharge ionization detector - Wikipedia

   en.wikipedia.org/wiki/Pulsed_discharge...

   Eluants from the GC column, flowing counter to the flow of helium from the discharge zone, are ionized by photons from the helium discharge. Bias electrode(s) focus the resulting electrons toward the collector electrode, where they cause changes in the standing current which are quantified as the detector output.
