WebA helium ionization detector ( HID) is a type of detector used in gas chromatography . Principle [ edit] HID connected to a GC has the great advantage to use helium as both the carrier gas and the ionization gas. HID is an ion detector which uses a radioactive source, typically β-emitters, to create metastable helium species. WebThis simply explains why it can leave the balloon in directions other than down. The reason it can leave the balloon at all is that it is a very very small atom. It can fit, or be wedged, in between the larger molecules of the latex material. At the atomic scale the latex is like a woven fabric, and the helium is like a fine grain of salt.
