There is currently research being done in firing fossil-fueled power plants with an oxygen-enriched gas mix instead of air.

The term "break through" means the failure of the "scrubber" to continue removing carbon dioxide from the exhaled gas mix.

The concentration of oxygen in a gas mix depends on the fraction and the pressure of the mixture.

Oxygen analysers measure the ppO in the gas mix.

Nitrogen in a gas mix is almost always obtained by adding air to the mix.

The air conditioning labored constantly to adjust the gas mix and filter out the contaminants.

Remember, under normal circumstances the compressed air and gas mix is ignited by a spark plug.

Stars develop inside a protogalaxy when clouds of gas mix and collide.

Whether you're in vacuum or water, the suit doesn't care--it maintains a healthy pressure and gas mix regardless.

A two percent excess of C02 in the gas mix was enough to trigger harder breathing.
