Hello again,

I am wanting to hear the thoughts of people who have tried to give a partially filled container a squirt of a gas to remove the oxygen. CO2 is cheap and available in small pressurised containers for the aquarium business (it is used to give some boost to the plant life in the aquarium). Nitrogen might be found somewhere too - I haven't tried yet. The noble gases are found in the wine preserving business where (of course) they make all sorts of claims about the efficacy of using a noble gas ...

If one is removing oxygen won't CO2 suffice ? Perhaps for only a few chemicals - a developer or a fixer but not both ?

Experiences ?
