Use small glass serum vials with butyl rubber stoppers (Bellco)
which are partially filled with a saturated Na2SO4 solution and
stored upside down to block gas diffusion through the stopper.
Works well even with H2 for many days (you didn't say HOW long you
need to store the gas ;-). Check with standards...
