Figure 1.

Determination of preferential interactions (${\mu }_{23}/\text{RT}$) of trehalose with model compounds by osmometry. The excess osmolality, ΔOsm, is plotted versus the concentration product, m₂m₃. The error bar is propagated from the standard deviation of the multiple readings of osmolality of corresponding solutions for calculating ΔOsm. Lines are linear fits to Eq. 3, with the value of ${\mu }_{23}\text{/RT}$ given by the slope. The master plot is divided into four subplots (A–D) for clarity.
