Methods for collecting gases
Downward delivery for gases that are denser than air. (eg. hydrogen)
Upward delivery for gases that are less dense than air. (eg carbon dioxide)
Collection over water for gases that are not very soluble in water.
Collection in gas syringe when the volume of gas needs to be measured.
Methods for drying gases
