Abstract: By using centrifugal force, foaming liquids are degassed and the amount of certain liquid components determined by analyzing exiting gas. Liquid fed to a rapidly rotating beaker is spread as a thin film while gas is forced out without foaming. This film is pressed to the beaker bottom and out through holes to the inside of a casing from where it runs out for collection. Air is blown into the beaker, whose interior is divided by a baffle. A minor amount of air exits through an annular gap between the baffle plate and the beaker wall, and a major amount through a blow-out tube. Volatile airborne liquid components are then analyzed.
