Oxygen, nitrogen and the rare gases
Nitrogen leaves the top of the column as a gas. Purity levels required by nitrogen users are becoming increasingly stringent and it may be liquefied again and redistilled. It is unusual for the nitrogen to have an oxygen content of more than 10 ppm and impurities contained in nitrogen for the electronics industry are measured in parts per billion.

When the metal bath is flushed by an inert gas , for example Argon, the atoms of the dissolved gas(-es) will recoine at the inert gas bubble surface and escape into the bubbles.There, the dissolved gas builds up a partial pressure which approaches equilibrium
Is Nitrogen Coustible? | Sciencing
A coustible substance can burn, and if nitrogen could burn, all life on earth would have been destroyed long ago. Nitrogen gas makes up some 78 percent of the earth''s atmosphere. Roughly 21 percent of the atmosphere is oxygen, and if it could coine with nitrogen in a coustion reaction, there would be none left for organisms to breathe.
