  2. Template:Infobox helium - Wikipedia

    Usually parameters reproduce the value, and the template adds the SI unit or additional standard text. While the topic is technical, we can strive to make the result readable text, and even verbose. For example, this is why the template writes "(at 0 °C)". For this, you may want to experiment with parameter input too - or propose improvements.

  3. Radionuclide identification device - Wikipedia

    en.wikipedia.org/wiki/Radionuclide...

    A radionuclide identification device (RID or RIID) is a small, lightweight, portable gamma-ray spectrometer used for the detection and identification of radioactive substances. [1]

  4. Helium ionization detector - Wikipedia

    en.wikipedia.org/wiki/Helium_ionization_detector

    An HID connected to a gas chromatograph (GC) has the great advantage to use helium as both the carrier gas and the ionization gas. An HID is an ion detector which uses a radioactive source, typically β-emitters, to create metastable helium species. [1] The radioactive source ionizes helium atoms by bombarding them with emissions.

  5. Ion mobility spectrometry - Wikipedia

    en.wikipedia.org/wiki/Ion_mobility_spectrometry

    IMS instruments are extremely sensitive stand-alone devices, but are often coupled with mass spectrometry, gas chromatography or high-performance liquid chromatography in order to achieve a multi-dimensional separation. They come in various sizes, ranging from a few millimetres to several metres depending on the specific application, and are ...

  6. 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.

  7. Automatic target recognition - Wikipedia

    en.wikipedia.org/wiki/Automatic_target_recognition

    Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.
