3 Ways to Test for CO₂ - wikiHow

22/6/2020· Collect a CO 2 sample. To begin your test, you will need a sealed test tube filled with collected gas. You can collect carbon dioxide in a gas jar, a boiling tube, or another airtight container. Collection is usually performed over water in a beaker. CO 2 gas is denser than air, so you can collect it using "downward delivery" or a gas syringe.
