Figure 3

Variations of the stability of VOCs sampled in two types of airbags after 24 h. (a) 2,2DMC3. (b) Isopentane. (c) 2-Methyl-2-butene. (d) Cyclopentane. (e) Trichloromethane. (f) 3-Methylpentane. (g) Benzene. (h) 3,3-Dimethylpentane. (i) 2-Methylhexane. (j) 2,3-Dimethylpentane. Ct (ppb), the concentration of the target organic matter after storage for “t” in the airbags; Ci (ppb), initial concentration of target organic matter.
