Whilst the ember at the tip is still glowing hot, the splint is introduced to the gas sample that has been trapped in a vessel. [4]
Four items are required for gas collection with a pneumatic trough: [2] The trough itself, which is a large glass dish or a similar container. A gas bottle (or bulb), to hold the gas collected.

The gas in a glovebox is pumped through a series of treatment devices which remove solvents, water and oxygen from the gas.

The prepared gas is usually impure, contaminated with fine aerosol of the reagents and water vapor. The gases may need to be filtered, washed and dried before further use.
