There may be materials in the wall of the reactor or the mesh that come out gradually. Also, if you bake it at the wrong stage, you cause materials to stick to the walls which are very difficult to get rid of. You need to check for them before you bake. Mizuno spelled out his methods in the paper. He said to use a mass spec. Other experts agreed with him. This experiment is hard enough to do with a mass spec and with the other recommended tools. People should not make it harder, or add to the unknowns and the guesswork. People who ignore the instructions may succeed despite that, but if they fail we will not know why. It is not really my business. My only concern is that they and others will say the instructions and the original experiment were flawed, even though they did not follow the instructions or do the experiment.
