Hello: I culture Propane Eating Microbes. I culture them

Resolved Question:


I culture Propane Eating Microbes.
I culture them from soil in a water solution, with about 4 ounces of water in a glass jar.
I seal the jar, then I pump propane into the jar through a hole in the lid.
That is then sealed.
I assume what exists in the jar, is the water, a column of propane floating above the water, and the lighter gasses such as 02 above that.
I need a way to see the propane either directly or indirectly, so I can monitor changes in its quantity (volume) as it is consumed.
I am told some methods won't work due to the glass jar.
I was wondering about UV light as some Hydrocarbons are illuminated by UV light-I think.
I don't want to do it by air analysis.
I would rather see the propane either directly or indirectly.

Any ideas??

Hello, welcome to Just Answer.

For seeing directly you could use a gas imaging camera (like they use in petrochemical industry), but those are expensive.

As the reaction is very slow you could use a laser at an angle and measure the refraction angle.

You could also use a speaker/mic gap and detect the variation in the speed of sound.

Both those method need to take in account the pressure variation in the jar.
