  2. Photoionization detector - Wikipedia

    en.wikipedia.org/wiki/Photoionization_detector

    A photoionization detector or PID is a type of gas detector. Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per billion to 10 000 parts per million (ppm). The photoionization detector is an efficient and inexpensive detector for many gas and vapor analytes.

  3. Gas detector - Wikipedia

    en.wikipedia.org/wiki/Gas_detector

    Gas detector. A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. 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 ...

  4. Tracer-gas leak testing - Wikipedia

    en.wikipedia.org/wiki/Tracer-gas_leak_testing

    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 ...

  5. Helium mass spectrometer - Wikipedia

    en.wikipedia.org/wiki/Helium_mass_spectrometer

    A helium mass spectrometer is an instrument commonly used to detect and locate small leaks. It was initially developed in the Manhattan Project during World War II to find extremely small leaks in the gas diffusion process of uranium enrichment plants. [1] It typically uses a vacuum chamber in which a sealed container filled with helium is placed.

  6. Hydrogen sensor - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_sensor

    A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. [1]

  7. Ion mobility spectrometry - Wikipedia

    en.wikipedia.org/wiki/Ion_mobility_spectrometry

    Ion mobility spectrometry. Ion mobility spectrometry (IMS) It is a method of conducting analytical research that separates and identifies ionized molecules present in the gas phase based on the mobility of the molecules in a carrier buffer gas. Even though it is used extensively for military or security objectives, such as detecting drugs and ...
