Helium capture from air

WebBoth helium and hydrogen are considered lifting gases because they are lighter than air. In fact, they are so light, that when these gases are released into the atmosphere, they disappear into space. This is one of the reasons why helium capture is so important – as helium is a nonrenewable resource and its supply is limited on earth. WebThe development of the electron capture detector (ECD) has made such direct measurements possible [Wentworth 1973, Rasmussen 1976], a nd GC-ECD has been used to measure N 2 O in air [Czepiel 1995 ...
