Gas Gang Chloroform, Carbon Monoxide, and Carbon Dioxide. Whereas the Metal Men were approximately the same size as Doctor Magnus, the Gas Gang were anywhere from one-third to twice his size. On Chloroform's initial attack, it caused the Metal Men to break out in fits of hysteria ala Nitrous Oxide (Laughing Gas) which Doc Magnus said was chloroform's initial effect. Before Lead could wall them off, Mercury literally "broke up laughing", opening Oxygen to attack and causing the Metal Men to begin to rust. During the chase Carbon Monoxide (called "CM" by Carbon Dioxide) attempted to poison them with fumes, while Carbon
Inert gas sources rich in this element, through cryogenic distillation or membrane separation. For specialized applications, purified inert gas may be produced by specialized generators on-site. They are often used aboard chemical tankers and product carriers (smaller vessels). Benchtop specialized generators are also available for laboratories. Because of the non-reactive properties of inert gases they are often useful to prevent undesirable chemical reactions from taking place. Food is packed in inert gas to remove oxygen gas. This prevents bacteria from growing. It also prevents chemical oxidation by oxygen in normal air. An example is the rancidification (caused by oxidation) of edible oils.
