This is not a purely isogeochem question, but I'm sure some people here have experience with H2 and CO gases. I'm helping design an experiment where H2 and CO gas are eventually going to be mixed and vented out, with flows in the 1 to 50ml/min range. I am wondering whether connecting the vent line to a fume hood evacuation system is enough to make sure no CO makes it into the room and how flammable/explosive such a flux of H2 might be when in contact with air. What do people usually do with these gases?
Of course we will follow the local safety procedures and so on, but any practical advice is appreciated!
