I am currently writing the experimental section for a thesis in chemistry. Someone, who did the reaction I want to describe, wrote: "the gas was bubbled into the reaction mixture at such a rate that almost no excess gas was detected." However, to me, the wording rather seems like lab slang.

The following is a list of what I found

  • the gas was passed into the solution (Link) I have never heard anyone say this and I don't really like it, but if this is right, I will have to accept it.
  • the gas was introduced to/into (which?) the solution
  • the gas was injected into the solution

For a better understanding of what I am aiming for: The gas was added so slowly, that the bubbles hardly ever reached the surface before being absorbed/dissolved. So the pressure was quite low.

So, what would best describe the slow addition of a gas to a solution?

  • The first word I thought of was infuse but I'm not sure if it is the best choice for this context.

    Infuse looks pretty good. It occurs in a lot of contexts like "The Technology is a unique method of infusing gas into liquids..."

  • To me, infused feels more like it is used in connection with liquids being infused. But I guess it could work.

    If you use gas being passed, you'll have a hard time getting your advisor to take your thesis seriously. (en.wiktionary.org/wiki/pass_gas)

  • @mathewb Yes, I know. I was afraid of that. :D

Gas can be introduced into a liquid or into a container of some kind.
