Apparatus is described for absorption of carbon dioxide released under controlled conditions from the container. The carbon dioxide absorbed in the gas‐washing bottles of this apparatus is determined volumetrically by successive titrations to thymolphthalein‐phenolphthalein and methyl orange end points, whilst the gas remaining in the main absorption flask is determined gasometrically. Calibration and calculation are described, the required carbonation figure being obtained from the sum of the two individual measurements. For bottles and cone‐topped cans, conventional piercing tools will suffice for penetration of the container; for flat‐topped cans a described device is used for connection to the absorption apparatus by means of transparent tubing.
