AB  - An apparatus is described in which the air exhaled by experimental animals is continuously extracted, permitting the collection of successive samples for the determination of volatile substances excreted by this route. Carbon dioxide output may be determined simultaneously by using a second extractor. The efficiency of the method has been checked with known concentrations of trichloroethylene and carbon dioxide in air.
