2. Flame ionization detector - Wikipedia

   en.wikipedia.org/wiki/Flame_ionization_detector

   The design of the flame ionization detector varies from manufacturer to manufacturer, but the principles are the same. Most commonly, the FID is attached to a gas chromatography system. The eluent exits the gas chromatography column (A) and enters the FID detector’s oven (B). The oven is needed to make sure that as soon as the eluent exits ...

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. Gas chromatography ion detector - Wikipedia

   en.wikipedia.org/.../Gas_chromatography_ion_detector

   This current is amplified and is the signal generated by the detector. The higher the concentration of the component, the more ions are generated, and the greater the current. Some early FIDs actually used two metal grids as their ion detectors. However, more efficient designs have been developed, so few current ion-type detectors use two metal ...

5. Gaseous ionization detector - Wikipedia

   en.wikipedia.org/wiki/Gaseous_ionization_detector

   The term "gas proportional detector" (GPD) is generally used in radiometric practice, and the property of being able to detect particle energy is particularly useful when using large area flat arrays for alpha and beta particle detection and discrimination, such as in installed personnel monitoring equipment.

6. Chromatography detector - Wikipedia

   en.wikipedia.org/wiki/Chromatography_detector

   A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.
