The volatile components in the cabin atmosphere of Skylab 4 at various times during the mission were concentrated and analysed. More than 300 compounds could be detected by high-resolution gas chromatography with differences in concentration of as much as six orders of magnitude. 107 substances were identified by mass spectrometry, covering a molecular-weight range of approximately 60 to more than 500. Thec oncentrations of 80 compounds were determined for three samples taken on days 11, 47 and 77 of the mission. The composition of the volatiles in the spacecraft's atmosphere differs significantly from other environments. A wide variety of various silicon compounds, mostly methylated siloxanes of molecular weight up to 584, was detected. Fluorocarbons (Freons) werde also present.
