Science Buddies: "Ask an Expert"

Im doing some preliminary research and trying to figure out something for a project/product, this is of personal interest to me and also maybe an idea. I know noble gases are commonly used to preserve many things and I was wondering if Argon is a good choice to start with preserving moisture sensitive organic matter. I found some info that was relevant, but id like to know how does the argon effect the moisture of the contents? I read that argon is dry, doesnt hold moisture or reacts with water, and brings the moisture level down to about 1%. It sounds to me like argon would be an okay gas to start with, but id just like to confirm that this is good for maintaining the moisture too? I was going to experiment with air/gas percentages too. any info would be helpful thank you.

Hi khaosodensland,

Storing materials under an argon atmosphere will prevent oxidation or other reactions that might occur in air. Storage under argon or dry nitrogen could help prevent moisture changes. And a good, air tight seal on the storage container should help.

I hope this helps. Please post again if you have more questions.
