Well that was another fun dog bone experiment to watch. After all the discussion on a leaking inner chamber, someone wisely decided to abandon the alumina cylinder for stainless steal and add a pressure sensor to it! Unfortunately it took way to get the noise out of the pressure readings, so it wasn't much help in seeing the decomposition of LiAlH4 or seeing when the leak occurred. After the transducer was fixed, you could see the pressure drop linearly from 100psi to about 18psi indicating a leak. I think that experiment is worth another try. The only suggestions to add would be to find an isolated ground for the pressure transducer and second, verify with Omega that that pressure transducer can be used to measure hydrogen gas pressure.
