Fixed gases in the vapor phase of MSS

Ishiguru and Sugawara in 1980 (1884) cataloged the components of tobacco smoke. In their review, they listed 1889 components of tobacco smoke [see Table 1 in (1884)]. They commented that the number could be about 2500 but they had omitted those components that were only partially identified. Among the components that they discussed were the fixed and variable gases in tobacco smoke. 

In 1982, Dube and Green (1067) calculated the contribution of the fixed gases from 500 mg of unfiltered cigarette MSS. From 500 mg of whole smoke, 22.5 mg was the wet 

In 1996, Green and Rodgman (1373) summarized all the historical and currently used analytical methods for the identification of chemicals isolated from tobacco and tobacco smoke. Their review is so complete and so well documented that the reader is directed to read their review article to determine the analytical method best suited for the analysis of a particular chemical constituent in tobacco and smoke. All of the past and current methods for the determination of fixed and variable gases in tobacco and tobacco smoke can be found in their article and will not be included in this chapter. Only a few specific examples of analytical methods for the most important variable gases will be provided (1884).
