Helium - Wikipedia

2019-4-23 · Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating. Helium at low temperatures is used in cryogenics, and in certain cryogenics appliions.

SF6-alternative gases for appliion in gas-insulated

The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases.

GC with Electron Capture Detector (GC-ECD)

Gas Chromatography – Electron Capture Detector or GC-ECD is a technique used to analyse halogenated compounds and is primarily used in the environmental, forensic and pharmaceutical markets. Within an ECD, when certain molecules pass by the detector, they capture some of the electrons in the sample and this reduces the current measured.
