Figure 1. Relationship between mean odor score and concentration of VC/VSC in liquid or gas phase. Plots A and B show VCs in liquid phase; C shows VSC in gas phase. Each point shows the mean score of seven odor judges ± SEM error bars.

Figure 2. Relationship between odor score and gas phase concentrations. For H2S and CH3SH, the gas concentrations were those set by experiment. For odorants in liquid phase, the equivalent head-space gas phase concentration was calculated according to Henry law constants (see text for details). Regression lines are extrapolated to y = 0 (the odor threshold) and y = 5 (saturation). Points and error bars have been removed for clarity. The slope for TMA (regression line 7) shows alternate projections for one-site binding (unbroken line) or two-site binding (dashed line).
