Trapping and Analysis of the Gas Phase of Cigarette Smoke/Zur Gewinnung und Behandlung frischer Gasphase aus Cigarettenrauch

The gaseous part of cigarette smoke was brought into contact with the surfaces of different materials such as glass, stainless steel, silicone rubber, and condensed gas phase. Subsequent analysis by gaschromatography shows that the gas phase may be even less stable than is generally assumed. Inert as well as reactive components are reduced by a short surface contact, the former up to 50, the latter up to 300 %. Using a specially designed large syringe made of teflon and steel we observed the lowest loss of smoke constituents caused by trapping the gas phase at room temperature.
