MS-5A column is definitely suitable for high-resolution separation of permanent gases but Porapak Q column usually use in food industry analyzes. So I prefer MS-5A column for separation of H2 and O2 from water splitting reaction and I would suggest GC-MS measurement instead of GC for this purpose.

The problem is not to separate H2 and O2, but to separate O2 and N2. The latter is always present as a contaminant from air. The best would be a molecular sieves capillary column with Ar and TCD. The T< 100C is advised. Just try. Don't forget to bake your column from time to time at ~ 180C overnight to remove adsorbed water.
