Abstract: Most scientists in the world of gas chromatography (GC) will advise you not to use nitrogen because it is considered a “dinosaur” gas and, instead, use helium, which offers shorter analysis time. But, wouldn’t it be very nice if we could make nitrogen work for applications where helium is not an option?
