Airgas, among other companies. You can buy plenty of gases for various applications. I'd rather buy because it's a more accurate measurement. I wouldn't be able to get an exact amount of hydrogen from electrolysis of water. Too many chances for error in my opinion.

Hi all. Doing a project for work. I want to mix hydrogen gas (among other gases) in a closed loop system of mineral oil. If I buy a 1 cubic ft bottle of hydrogen, the ppm should be irrelevant because it's all hydrogen right (theoretically)? It would be 1 million ppm?? Finally, if I mix 1 cu. ft. (roughly 28.3L) of hydrogen with 5L of oil, how do I find the new ppm of hydrogen? Would it be: (1000000 *28.3 + 0* 5)/ 33.3? Or does mixing a gas and liquid require a different calculation for ppm? My goal is to get roughly 200-250 ppm in the mixture of 5L, so I don't think I need that much hydrogen.

Hi all. Need to bounce ideas for a project at work. I would like to dissolve hydrogen gas (among other gasses) into a closed loop system of mineral oil. With Henry's law, I can lower the temperature and increase the pressure to help. But if I don't help dissolve it along via pressure and temperature manipulation, the gas will just sit on top on not mix right? If this closed loop has a pump to circulate the oil, will that be enough agitation to help dissolve the gasses? Also, how would I calculate the new concentration? The gas has a given ppm sent by the manufacturer, and the oil has a certain volume based on the container I choose. Is it just some simple math? Regards.
